Digital inputs

The jumper is located inside the unit on the base plate slightly below the middle and to the right of the 4 relays.

Digital inputs	Use	Terminal	Note
Input 1	Motor status (0 = Stopped, 1 = Running)	DI1 (PNPPNP is a positive signal (plus). or NPNNPN is a negative signal (minus).)	If the JPDI1 jumper is in position N, the DI1 signal must be 8-40 VDC (PNPPNP is a positive signal (plus).). If the JPDI1 jumper is in position S, the signal must be between GND and DI1 (S0IEC 62053-31 Class A S0 standard for pulse signals./NPNNPN is a negative signal (minus).).
Input 2	Sensor open (0 = Not open, 1 = Open)	DI2 (PNPPNP is a positive signal (plus). or NPNNPN is a negative signal (minus).)	If JPDI2 is in position N, the DI2 signal must be 8-40 VDC (PNPPNP is a positive signal (plus).). If JPDI2 is in position S, the signal must be between GND and DI2 (S0IEC 62053-31 Class A S0 standard for pulse signals./NPNNPN is a negative signal (minus).).
Input 3	Sensor closed (0 = Not closed, 1 = Closed)	DI3 (PNPPNP is a positive signal (plus). or NPNNPN is a negative signal (minus).)	If JPDI3 is in position N, the DI3 signal must be 8-40 VDC (PNPPNP is a positive signal (plus).). If JPDI3 is in position S, the signal must be between GND and DI3 (S0IEC 62053-31 Class A S0 standard for pulse signals./NPNNPN is a negative signal (minus).).
Input 4	Road sensor outside area (0 = No vehicle detected, 1 = Vehicle detected)	DI4 (PNPPNP is a positive signal (plus). or NPNNPN is a negative signal (minus).)	If JPDI4 is in position N, the DI4 signal must be 8-40 VDC (PNPPNP is a positive signal (plus).). If JPDI4 is in position S, the signal must be between GND and DI4 (S0IEC 62053-31 Class A S0 standard for pulse signals./NPNNPN is a negative signal (minus).).
Input 5	Road sensor inside area (0 = No vehicle detected, 1 = Vehicle detected)	DI5 (PNPPNP is a positive signal (plus).)	Use only PNPPNP is a positive signal (plus). signal.
Ground	Ground for inputs 1..5	GND	Must always be connected.

Relay outputs

Maximum load is 5 A @ 250 VAC / 30 VDC.
Maximum inductance for switching is 20 mH per output.

Relay outputs	Use	Terminal	Note
Output 1	Open (0 = Closes, 1 = Opens and stays open)	R1A and R1B (NONormally open.)	For sliding gates, doors, and barriers.
Output 2	Open (0 = Closed, 1 = Closes and stays closed)	R2A and R2B (NONormally open.)	For carousels where 2 directions must be controlled.
Output 3	Status (0 = No access control, 1 = Access control enabled)	R3A and R3B (NONormally open.)	A lamp can show whether access control is enabled.
Output 4	Fault (1 = System fault)	R4A and R4B (NONormally open.)	A lamp can show when the system has a fault.

DC output

The jumper is located inside the unit on the base plate slightly below the middle and on the right side.
If the 12 V output is used, the VikMoteController with built-in GSM and data logger. must be supplied with 24 VDC or 230 VAC.
If the 24 V output is used, the VikMoteController with built-in GSM and data logger. must be supplied with 230 VAC.

DC output	Use	Terminal	Note
DC output 12/24 VDC, max 500/250 mA	Extra 12/24 VDC supply voltage, max 500 mA @ 12 V and max 250 mA @ 24 V	DCOUT	Factory set to 24 V, jumper fitted.
Ground	Ground for DC	SGND	-
