The back of the APM2 has electrical connectors labeled with their function. The mating electrical connectors
(supplied) are color coded and labeled with the matching function.
Refer to the Advanced Pressure Monitor II User's Guide (MKT-0263) for detailed wiring instructions.

2.2.5 Remotely Switching Alarm Setpoints

The APM100 model uses dry contacts to switch pressure setpoints between positive and negative, whereas the
APM2 uses an input voltage: 0, 5 or 10 Volts to switch pressure setpoints between negative-neutral-positive
respectively. If this function was used on the APM100 product, adaptations will need to be made to restore their
function with other equipment or devices that will generate the 0, 5 or 10 Volt signal.
