LCO500 Laboratory controller
LCO500 Laboratory controller Functional description ● Performance features Functional description The LCO500 laboratory controller automatically and decentrally balances the setpoints for laboratory room air control (room supply air and exhaust air). The room air change rate requirements of DIN 1946, Part 7 are taken into account and are freely programmable. Negative room pressure (in laboratories) or positive room pressure (in clean rooms) may be set by a percentage relative to the room exhaust air or with a fixed offset (e.g. 300 m3/h). The negative room pressure is determined using the following formula: Room supply air = exhaust Negative room pressure air * 0.9 = 10% Room supply air = exhaust air - 300 Offset = 300 m3/h And the positive room pressure is calculated with the following formula: Room supply air = exhaust air * 1.1 Positive room pressure = 10% Room supply air = exhaust air + 300 Offset= 300 m3/h Where there is sufficient air intake and circulation (e.g. around doors), the room supply/exhaust air ratio should be established using a calculated percentage rather than a fixed offset. The percentage ratio should be approx. 10...15% in order to compensate possible measuring inaccuracies of approx. 10% in the entire system (e.g. excessively low upstream and downstream flow routes). In airtight rooms, i.e. where there is insufficient air intake and circulation, a fixed offset must be added (positive room pressure) or subtracted (negative room pressure). Room balance in laboratories Demand-related volume flows change very quickly (< 2 s) in laboratories and must be compensated at a sufficiently high control speed in the supply and exhaust air. A prescribed negative or positive room pressure in the laboratory must be maintained safely and conclusively at all times. Via the analogue inputs, the SCHNEIDER LCO500 laboratory controller balances up to 10 connected consumer loads with the individual exhaust air volume flow actual values and cumulates the total and the difference to a prefined value. These values are used setpoints for the SCHNEIDER VAV-A variable volume flow controllers which regulate the required volume flow for the room supply air (total) and the additional room exhaust air (difference). LON connection to the building services management (BSM) The LCO500 laboratory controller has been specially designed for cost-efficient LON connection (optionally BACnet) of the entire laboratory. All LCO500 inputs and outputs (digital and analogue) are available via standard network variable types (SNVT). Thus, a cost-efficient, room by room connection to the multisupplier BSM can be implemented. Technical documentation LCO500 • Date: 11/2009 • www.schneider-elektronik.com Each room only occupies one node of the LON network, which considerably reduces the number of routers that are required in a project. By means of the LON control, the LCO500 laboratory controller fulfills the function of a DDC sub-station. Summated balances (room supply/exhaust air) are available in the BSM as standard network variable types (SNVT). Performance features 10 analogue inputs (exhaust air actual values of the fume hoods/consumer loads) are summated and assigned to one or more analogue outputs (max. 8) 8 analogue outputs 0(2)...10V DC for freely programmable groups. Any analogue inputs (1 to 10) can be connected to any analogue outputs (1 to 8). Setpoint balancing for room supply air and an additional room exhaust air (difference in relation to the freely programmable room air change rate) Defined maintenance of the negative pressure (laboratory) or the positive pressure (clean room) Decentralized, automatic room balancing, relieving the load on the building services management (BSM) Calculation of the room diversity and free programming of the functionality 8 digital inputs (optionally galvanically separated) for switchable consumer loads (on/off), room operating panel (suspension of night-time operation), malfunction notifications, alarms, etc. 8 relay outputs with potential-free changeover contact for daytime/nicht-time switching of the fume hoods, light (on/off), heating control, room group malfunction notification, etc. Internal optional 24V DC/75 W switching power supply for direct 230V AC power connection and for providing the 24V DC supply voltage for a maximum of 8 connected VAV-A (variable volume flow controllers) Mains voltage failure-safe storage of all system data in the EEPROM Router functionality for the laboratory with LON300 field bus module (optional), Transceiver FTT-10A Removable plug and play LON300 or BACnet (optional) network card, thus easily adaptable to the central building services network.

The laboratory controller can actuate up to eight freely configurable volume flow controllers for room supply/ exhaust air (Aout1 to Aout8). The internal switching power supply (optional) provides the supply voltage 24V DC for a maximum of 8 volume flow controllers (VAV-A), which simplifies planning and makes implementation more costefficient. The analogue inputs Ain1 to Ain10 are summated and can be combined in any number of groups on the analogue outputs Aout1 to Aout8, which means that any type of configuration is possible. For example, up to eight laboratories each with a room supply air volume flow controller and a maximum of 10 fume hoods can be automatically controlled. As shown in room plan 1, as well as the room supply air an additional room exhaust air can be configured. Each room exhaust air volume flow controller requires an analogue input (actual value room exhaust air). Here the parallel connection to the building services management (BSM) and/or DDC is done via the input/output interface (optocoupler and relay) and can easily be implemented with the optional additional terminal rows. The group alarm is generated by serial connection of the individual alarm contacts and daytime/night-time switching of the fume hoods is done parallelly via the input octocoupler of each fume hood controller. At least one cable IY(St)Y 2x2x0.8 is required for this functionality. If the optional room control device RBG100 is also to be connected to enable room by room cancellation of night-time operation, a further IY(St)Y 3x2x0,8 cable is necessary. This makes it possible to implement the functions Light-day, Light-night and Button-cancel night-time operation. When requested to cancel night-time operation e.g. for one night, the BSM/DDC switches to daytime operation, which ensures safe working conditions (8 air changes) in the laboratory at night. The BSM/DDC must reserve both a digital input and a digital output for each function that is to be implemented. Table 1 shows the relationship between the function and the digital input/output of the controlling BSM/DDC.

Room plan 2 shows the interconnection of up to 9 fume hoods (Ain1 to Ain9) with the LCO500 laboratory controller. The laboratory controller can actuate up to eight freely configurable volume flow controllers for room supply/exhaust air (Aout1 to Aout8). The internal switching power supply (optional) provides the supply voltage 24V DC for a maximum of 8 volume flow controllers, which simplifies planning and makes implementation more cost-efficient. The analogue inputs Ain1 to Ain10 are summated and can be combined in any number of groups on the analogue outputs Aout1 to Aout8, which means that any type of configuration is possible. For example, up to eight laboratories each with a room supply air volume flow controller and a maximum of 10 fume hoods can be automatically controlled. As shown in room plan 2, as well as the room supply air an additional room exhaust air can be configured. Each room exhaust air volume flow controller requires an analogue input (actual value room exhaust air). LON network Cost-efficient connection to the multisupplier building services management (BSM) is achieved via the LON network through the optional field bus module LON300 (FTT-10A). With the extension of the digital malfunction alarm inputs (optional) all alarms of the individual fume hoods can be Thus the LCO500 laboratory controller fulfills the function of a DDC sub-station or a router.

Extended functions may also be implemented, e.g. remote maintenance. Through switching between daytime/nighttime and retrieval and comparison of the individual exhaust air actual values, this function can be checked in every fume hood. The LCO500 laboratory controller combines analogue technology with the advantages of LON bus technology and offers cost-efficient and safe room by room control and visualization via the BSM.

This applies both to the increase in exhaust air volume flow brought about by opening the fume hood sash and the reduction in exhaust air volume flow caused by closing the sash or by external switching to reduced operation (nighttime reduction). The room air change is defined in DIN 1946, Part 7 and can be calculated with the following rule of thumb: Minimum room air change Room air change rate 25m³/h x m² 25m³ per hour exhaust air volume flow, multiplied by the laboratory main floor space in m². With this formula the prescribed 8 room air changes can be achieved. During night-time operation the reduced figure of 4 room air changes is sufficient. In addition to the room air change requirements specified by DIN 1946, Part 7, air volume balance and maintenance of protective pressure (negative pressure in laboratories and positive pressure in clean rooms) as well as comfort criteria such as temperature, humidity and air movement must be taken into account. High-speed volume flow controllers High-speed variable exhaust air control (< 2 s) via fume hoods requires high-speed variable room supply air control (< 3 s). The high-speed control times mean that the defined negative room pressure can be maintained under all operating conditions. When a specific minimum level of room air change must be maintained, which cannot be fully achieved by the extraction units (fume hoods and other consumer loads), an additional volume flow controller for the room exhaust air is necessary. Via the LCO500 laboratory controller the additional room exhaust air controller always controls the difference between the technically induced exhaust air of the extraction units and the required minimum exhaust air volume flow. Room supply air is compensated based on the room exhaust air. Negative room pressure is achieved by supplying only approx. 90% (programmable) of the room exhaust air as supply air to the laboratory. Diagram 1 shows the addition of the total room exhaust air and compensation of the total room supply air as well as the increase in exhaust air on fume hoods and switchable consumer loads e.g. through opening of the sash and the resulting reduction in the additional room exhaust air (difference to the minimum room air change). The minimum room air change is thus always maintained at a constant level and is only increased when the exhaust air requirement of the fume hoods and switchable consumer loads increases further. During night-time operation a fixed reduced value is regulated, independent of the sash position of the fume hoods.
