7.3.1 Releasing Circuit Wiring
Wiring for the releasing circuit is shown in
below. SIG3 and SIG4 output circuits are
reserved for the releasing circuits. Solenoid EOL module (MP-320R/W) is used to supervise
the solenoid coil. If the solenoid is already fitted with the directional diode then only the 3.9K
Ω
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.

Dialer Wiring (US only)
If you have an FR-320D, there is a dialer on board and terminals marked Line 1 and Line 2
must be wired as shown in
below.
