Multi Point Controller LGC/LG2-04
1 Description
The PolyGard® Multi Point Controller LGC/LG2-04 is used for the monitoring and warning of sensor point
exceeding their stage setpoints. External Transmitters can monitor and warn of toxic, combustible and refrigerant
gases as well as temperature and humidity. The Controller LGC/LG2-04 can measure up to 4 analog (Gas)
Transmitters per EP module with 4 to 20 mA signals. Each Sensor Point (SP) can have five stage thresholds.
Each stage threshold can be asigned to anyone of the relays (R1…R5). The Controller can interface via 4 to 20
mA outputs to any compatible electronic analog control, DDC/PLC control or automation system.
The adjustable parameters and staged thresholds make this system very flexible for sensor measuring and
control.
The configuration of parameter settings and operation is easy to do without any programming knowledge.
PolyGard® Multi Point Controller LGC/LG2-04 must not be used in areas requiring explosion proof equipment.

2.3 Password Level
All changes of parameters and staged setpoint values are protected by four digit numeric Code (= password).
The code level 1 permits the operation of the LGC/LG2-04. This code level is intended for the customer. This code
can be individually changed in System Setup Menu with valid Code 2 Password.
With the code level 2 all parameters and set points can be changed, this code level is reserved for the service
technician.
A third code level permits activation or deactivation of sensor points (SP).
A password must be re-entered if 15 minutes goes by without the press of a push button.
All menu windows can be seen without a password required.

Malfunction management records the last 15 malfunctions with date and time stamps. In addition, “System Errors”
are recorded in “Error Memory” when the malfunction occurs. This history can be selected and cleared only by the
service technician level password.
A malfunction gets over laid on text message in the starting menu. When the failure happens a relay, which is
defined in the system setup as „Failure relay“ is activated. The red LED in the front of the Controller flashes.
During the malfunction of a sensor point (SP) relays that are assigned for sensor are activated. These are defined
in the menu „SP Setup“.

The manual operation of the relays occurs in the menu „Relay Status”. If a relay is in the manual ON or OFF
status, the yellow LED at the Controller is on continuously.
The external operation of the alarm relay over an assigned digital input has the priority before the manual
operation in the menu "Relay Status" and exceeding the Stage set point assigned.
In the menu „Relay Status“ any manually operated relays can be reset by selecting the "Automatic" mode.
Acknowledgment of the relays in Latching mode also is a function in this menu.

1 Range Recommendations for Polygard sensors
2 During oxygen measurement falling signal!
3.6.3 Measuring range
The measuring range can be defined from 10 to 10000 . The measuring ranges in the above table are typical and
only recommendations actual ranges see the sensor manufacturing specifications.
The measuring range must agree with the signal (4 to 20 mA) attached transmitters.
(4 mA = Display=0, 20 mA = Display Measuring range = max. point)
3.6.4 SP Signal
Gas transmitter with electro-chemical - or catalytic bead sensors is linear for gas concentration proportional 4 to 20
mA signal.
Semiconductor gas sensors that are not linear and have a (exponential) signal. This signal leads to a non-linear 4
to 20 mA signal from the gas transmitter.
The Controller LGC/LG2-04 has the capability to monitor both type of gas transmitters, and other linear 4-20 mA
sensors. The type of signal is defined in this menu.
Symbol Description Setting
Status Function
SP 01 Sensor Point Selection SP No.

not linear = Transmitter with non linear Output signal (future).

3.6.5 Stage/Setpoint / Hysteresis
For each sensor point can have five staged set points. If the measured level is greater than the adjusted stage/set
point, the associated stage is set. If the level falls below the stage/setpoint plus the hysteresis then the stage
returns to original condition.
It is not necessary for stage/set point to be defined at the measuring range end point.
For O2measurement on depeletion consider when defining stage setpoints that stages will be set on a falling measuring
signal!

3.7.4 Average Function
The Controller calculates for each active sensing point the arithmetic average value from 10 measurements within
the time unit defined in the menu „ AV-time“. This average value is indicated in the menu “Sensor Readings” near
the current value. At each Sensor Point the control mode of current value or average value for the Stage/Setpoint
evaluation is defined.
The evaluation of the control mode average value is overlaid by the current value, if this exceeds Stage/Setpoint
defined in the menu „AV-Overlay”. The overlay is delayed by the time factor set in this menu.

3.7.7 Analog Output
The Controller has two analog outputs (AO) with 4 to 20 mA signal per control module. Each of the analog outputs
can be assigned the signal of one or more sensor points. The assignment occurs in the menu „SP Setup“ for
each SP. The sensor point sends the signal that is defined in the menu „C/A Mode“.
The Controller determines from the signal of all assigned sensor points the minimum, the maximum or the average
value and sends this value to the analog output. The determination of which value is sent is defined in this menu
„Analog Output X“. The analog output can be calibrated with for 4 and 20 mA. In addition the AO can be adjusted
with an ampere meter attached (measuring range 25 mA) then respective AO factor can be changed to adjust the
analog output 4 and/or 20 mA . During AO calibration no evaluation is made of the sensor point signals. This
calibration is factory-set. The factors should only be changed if you have an accurate amp meter.

3.7.9 Power On Time
Sensors need a warm up period, until the chemical process of the sensor reaches a stable condition. During this
warm up period the current signal can lead to unwanted false alarm. Therefore the Controller starts reporting after
switching on of the power supply and the delay On Time is passed. While this time runs off, the Controller does not
report alarms. The power on status is displayed in the display.
Symbol Description Default

30 s Power On Time 30 s XX = Define the Power On Time (sec.)
3.7.10 Activation of expansions modules
The Multi point Controller can have expansions modules; therefore only activate Expansions modules for every
four sensor points in addition to the controller module.
