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%
air - 300
Offset = 300 m3/h
And the positive room pressure is calculated with the following formula:
air * 1.1
Positive room pressure
= 10%
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

Application example ● Laboratory controller with I/O connection to the BSM
Room air control with laboratory controller and
I/O connection to the BSM
Room plan 1 shows the interconnection of 3 (maximum)
10 fume hoods (Ain1 to Ain10) 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 (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 air change rate ● Room air control diagram
Laboratories with multiple fume hoods and extraction units
have complex room supply and exhaust air control requirements.
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.

Tender specification LCO500
LCO500 laboratory controller for balancing room supply
air (total) and room exhaust air volume flows (difference to
maintenance of the room air change rate) in laboratories.
Balancing of 10 connected consumer loads. Eight analogue
outputs, 8 relay outputs and 8 digital inputs, optically decoupled. Can be extended by cascading 9 analogue inputs and
7 analogue outputs for each additional LCO500 laboratory
controller.
All inputs and outputs are freely programmable and can be
adapted to existing room volume flow controllers and/or frequency inverters.
Laboratory controller with integrated microprocessor and 2
independent watchdog switches. All system data are saved
in the mains voltage failure-safe EEPROM. Separate terminal board for fast, simple cable connection. Suitable for all
fume hood constructions.
Direct 230V AC power connection for the internal switching
power supply to provide the 24V DC/75 W supply voltage
for a maximum of 8 room air volume flow controllers. Programming via RS232 interface with laptop or service module or optionally via the LON network.
Optional extensions:
Retrofittable terminal rows for room functions from/to DDC.
Redundant monitoring of room pressure.
Monitoring of the exceedance of a programmable maximum
room air volume flow with optical and/or acoustic alarm
(transparent signalling of the diversity factor.
LON connection via retrofittable LON module LON300, with
FTT-10A, free topology, standard network variables (SNVT)
with router functionality.
