SWITCH OPERATION
The unit is factory set for momentary operation
To select latching operation cut the wire link X
LED INDICATION
The unit is factory set for on board LED indication
To select remote LED indication
POWER CONNECTION
Connect Live, Neutral and Earth wires to 3 way terminal block (L,N,E marked on pcb)
LOAD CONNECTION
Connect switched load to the 6.3mm blade terminals marked NO, C, NC
SWITCH CONNECTION
Connect a 5.6 Kilohm 0.25W resistor onto one of the switch terminals. This enables the
module to differentiate between a valid switch closure and a short circuited switch line.
Connect the switch/resistor combination to the I1 and I2 (earth) input terminals using either
the 2 wire or 1 wire configuration shown below
MOUNTING
Finally, chassis mount the unit onto the two fixing pillars using M3 screws (40mm vertical
centres, 17mm horizontal centres)
SWITCH WIRING DIAGNOSTIC TEST
Set the connected switch to off and switch on the AC power to the unit. The LED will
illuminate and blink for approximately 5 seconds if the length/capacitance of the switch wiring
is within acceptable limits.
INSTALLATION
‘spin cut’ the copper pad marked LED OFF
to disconnect the on board LED
connect the remote LED to the 2 pin
Molex header (ensure LED cathode
connected to pin K)
connected switch is closed
relay alternately energises/de-energises
each time the connected switch is closed
and opened
relay energises whilst the
