A) Potentiometer for setting the volume of the buzzer (VOLUME).
B) Potentiometer for setting the delay time (DELAY) for pump/solenoid 1.
Adjustable from 0 seconds to 5 minutes
C) Potentiometer for setting the delay time (DELAY) for pump/solenoid 2.
Adjustable from 0 seconds to 5 minutes
D) Dip-switch for pause time (LOCK-OUT). Lockout times can be set in 5 minute increments up to 75 minutes by
setting the dipswitches as follows:
DIPSWITCH 1
DIPSWITCH 2
DIPSWITCH 3
DIPSWITCH 4
E) Jumper for CALIBRATION
F) Input connector for level float switch:
LEV1 for pump 1
LEV2 for pump 2
G) Input connector for remote control:
TRIG.1 for pump/solenoid 1
TRIG.2 for pump/solenoid 2
The voltage to be applied may vary from 20 to 230
H) Jumper for selecting the power supply voltage of the device. The voltages that can be applied are 115 – 208 –
230 VAC.
I) Power-supply connector for device PWR
2.3 ELECTRICAL CONNECTIONS

CAUTION: The OPL BASIC has high voltage connected to the transformer. Always disconnect power
when servicing the unit.

All electrical connections to the OPL BASIC system should first be verified with a meter. Application of
incorrect voltage will permanently damage the unit and is not covered under warranty. Avoid wiring to
any power source that has large fluctuations in voltage and/or is prone to surges. Refer to the wiring
diagram in this manual for all power and signal connections. All wiring must conform to local electrical
codes.
2.3.1 Main Power Connection (Picture 2)
To wire main power connection:
 Check the voltage of the main power source and make sure that it matches one of the three available input
voltages (115/208/230 VAC) of the transformer;
 Move the jumper to the proper terminals to set the input voltage (Picture 2) before connecting the power supply:
 Disconnect all power from the laundry machine
 Connect leads from the main power source to the Power terminals on the circuit board (Picture 2).
