Product Setup
Refer to the appropriate series below for information on how to set up the product:
D65CE Series
Adjust the pick-up setting between the MIN & MAX values of the monitored current range of the unit.
The drop-out setting is fixed at 95% of the pick-up setting. The LED is Green when input voltage is
applied. The relay energizes (and the LED is Red) when the monitored current is above the pick-up setting. The relay de-energizes (and the LED is Green) when the monitored current is below the drop-out
setting & input voltage remains.
D65CEK Series
Adjust the pick-up setting between the MIN & MAX values of the monitored current range of the unit.
Then adjust the drop-out setting between 50 & 95% of the pick-up setting. The LED is Green when
input voltage is applied. The relay energizes (and the LED is Red) when the monitored current is above
the pick-up setting. The relay de-energizes (and the LED is Green) when the monitored current is
below the drop-out setting & input voltage remains.

Standard Current Monitoring
D65CH Series
Adjust the pick-up setting between the MIN & MAX values of the monitored current range of the unit.
The drop-out setting is fixed at 95% of the pick-up setting. Set the time delay on pick-up between 0.1 &
10 seconds. The LED is Green when input voltage is applied. The relay energizes (and the LED is Red)
when the monitored current is above the pick-up setting for a period longer than the set time delay.
The relay de-energizes (and the LED is Green) when the monitored current is below the drop-out
setting & input voltage remains.

Overcurrent Monitoring
D65CHK Series
Adjust the pick-up setting between the MIN & MAX values of the monitored current range of the unit.
Then adjust the drop-out setting between 50 & 95% of the pick-up setting. Set the time delay on pickup between 0.1 & 10 seconds. The LED is Green when input voltage is applied. The relay energizes
(and the LED is Red) when the monitored current is above the pick-up setting for a period longer than
the set time delay. The relay de-energizes (and the LED is Green) when the monitored current is below
the drop-out setting & input voltage remains.
D65CL Series
Adjust the drop-out setting between the MIN & MAX values of the monitored current range of the unit.
The pick-up setting is fixed at +5% of the selected drop-out setting. Set the time delay on drop-out
between 0.1 & 10 seconds. The LED is Green when input voltage is applied. The relay energizes (and
the LED is Red) when the monitored current is above the pick-up. The relay de-energizes (and the LED
is Green) when the monitored current is below the drop-out setting for a period longer than the set
time delay & input voltage remains.
