FACTORY CONFIGURATIONS
The device preset is as follows:
•
Range is 0-15 Vdc
•
R1 is set to 6 Vdc
•
R2 is set to 12 Vdc
•
Deadband is set to 3%
CALIBRATION AND SETUP
•
Set the INPUT RANGE jumper to the correct position for the signal to
be used. For example, if the input signal is 2-10 Vdc, select the 0-15 Vdc
range.
•
Set the deadband jumper to the desired value. This can be changed at
any time with the power on.
•
Connect the power supply and the input signal to the correct terminals.
•
Turn the power on and the POWER LED will light.
•
Apply an input signal equal to the R1 set-point.
•
Adjust the R1 pot clockwise until the RELAY1 LED goes out, then slowly
adjust the R1 pot counter-clockwise until the LED lights.
•
Apply an input signal equal to the R2 set-point and adjust the R2 pot the
same as for R1, watching the RELAY2 LED.
•
Test the operation by increasing the input signal and watch as R1 and R2
turn on at the selected set-points. Then decrease the signal and watch as
the relays turn off at the selected set-points minus the deadband.
