Products such as aerosol sprays, polishes, waxes and lubricants with silicones and non-catalysed silicone rubbers such as “silastic”, phosphate esters, and hydraulic fluids – will all damage catalytic sensors. Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 10 of 25... -
Page 11: Amplifier Pcb
3.2 Amplifier PCB The purpose of the Amplifier PCB is to convert the low-level electrical output of the sensor into a signal capable of driving various types of external indicator equipment such as the Ampcontrol GasGuard 4 Channel Controller. The Amplifier PCB requires a 12VDC operating voltage and transmits a signal of 4-20mA. At the lower end of the range, the 4mA signal level indicates a zero gas concentration. -

Page 15: Mechanical Installation Information
The connection terminals for GasGuard detectors are located within the enclosure. In order connect the incoming cable to the unit the cable must feed through the side mounted cable gland. Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 15 of 25... -
Page 16: Electrical Installation Information
Normal practice would be to isolate the cable screens at the Transmitter and connect the screens to earth adjacent to the Control units or power supply to the system. Remote sensor cable screens should be earthed at the transmitter. Uncontrolled Copy - Refer to Ampcontrol Website for Latest Version Page 16 of 25... -
