Releasing Circuit Wiring

INPUT CIRCUIT WIRING: FM APPLICATIONS MUST HAVE CLASS A
INITIATING CIRCUITS ONLY AND 90 HOUR BATTERY STANDBY OPERATION
Only addressable M500S and MIX-M500SAP supervised output modules can be used as a
releasing circuit.
If the releasing circuit is wired as Class B, supervision of the solenoid coil is performed by the
MP-3500R/W Solenoid EOL.
Wiring for the releasing circuit is shown in Figure 1.
Solenoid EOL module (MP-3500R/W) is used to supervise the solenoid coil. If the solenoid is
already fitted with the directional diode then only the 47K EOL resistor is used. The
supervisory current passes through the solenoid coil thus confirming the integrity of the
solenoid coil for open coil. The wiring is supervised for the open and short conditions.
