1.8.3
Sensor Monitoring Module (sensor-configured iL systems only)
This Module communicates with the Gas Module, the Pump Display Module (if fitted) and the
optional Interface Module accessories. The following sensors are connected to the Sensor
Monitoring Module:
•
LCDP pump-body and pump-motor water manifold temperature sensors (if fitted)
•
LCMB pump temperature sensor (iL600 systems only)
•
Water flow-switch.
The Module has a microprocessor which:
•
Monitors the status of the system.
•
Sends warning and alarm messages (see Section 1.10.2) to other Modules connected to the iL
system.
•
Shuts down the iL system if a sensor reading is outside the specified alarm range: see
Section 1.10.2. (Note that the safety sensors can also shut down the iL system; these sensors
are not connected to the microprocessor: see Section 1.10.3.)
1.8.4
Gas Module (sensor-configured iL systems only)
The Gas Module communicates with the Sensor Monitoring Module.

Controls and indicators
Refer to Figure 1-6. The controls and indicators on the front panel of the iL system are as follows:
Emergency stop switch (1)
Press this to immediately shut down the iL system in an
emergency: refer to Section 5.10.
Pump Display Module (2)
If fitted, use this optional accessory to control the iL
system: refer to Section 1.11.
Nitrogen supply pressure
regulator (3) *
Use this to adjust the nitrogen supply pressure.
Shaft-seal purge pressure
high and low LEDs (4, 5) *
These green LEDs are both on when the shaft-seals
purge nitrogen pressure is acceptable. The appropriate
LED is off when the pressure is too high or too low.
Power OK LED (6)
This green LED is on when the internal 24 V electrical
supply is on.
Running LED (7)
This green LED is on when the iL pumps are operating.
