4.2.1 MONITOR WIRING
POWER SUPPLY:
CAUTION:
Ensure to take all proper precautions when handling high
voltage power sources.
The monitor operates on 120 VAC, 60 Hz. A step down transformer
powers the internal circuitry and remote sensor/transmitters at low
voltages. The power supply connections are made at the power
terminal block located inside the monitor, see Figure 4.
RELAYS:
When 2 or 3 relays are included with the monitor, “Ice Cube” DPDT
relays are used. Two of the relays are set for different alarm
conditions and the optional third relay is a Fault relay. The contacts
are rated for 10Amps@250VAC resistive. For relay contact
arrangement, see Figure 5.
The AMC-1ACOs is shipped with relays factory configured per customer order, typically as de-
energized in the non-alarm state. If the user prefers to have relays in a normally energized
(failsafe) state see section 5.1.2 for jumper configuration.
All settings are factory configured, as per original customer order, for use with the installed
sensor. Certain user options however may be set according to preferences in the field.
