6.7 Start Delay
Adjust the start delay to the desired setting with a small screwdriver. The actual start of the unit is
delayed further by the soft start control or “walk in” that is engaged at the end of the delay se-
quence selected.
6.8 Over Voltage Protection [OVP]
6.8.1
The unit should be isolated from the load before adjustment. Therefore the output breaker should
be placed in the “off” position. Set the OVP setting to the maximum limit.
6.8.2
Select the “Test” mode for adjustment of the alarm. Using the “Test” adjustment control, adjust the
output voltage to the desired level. Monitor the output via the display panel meter or via a separate
D.V.M. connected to the “Test” jacks to obtain the accuracy beyond three digits.
6.8.3
Decrease the OVP level until the unit shuts down (the OVP LED will illuminate). Reset the unit by
turning the input breaker “off” and then “on”. The unit will now be in the “Float” mode.
6.8.4
To confirm the setting, decrease the test level, then place the unit in the “Test” mode. Increase the
output level via the “Test” control. The unit should trip out at the level as set in step 6.8.3.
6.8.5
Reset the unit as before by momentarily opening and closing the input breaker.
6.9 Under Voltage Alarm
6.9.1
The unit should be isolated from the load before adjustment. Therefore the output breaker should
be placed in the “off” position. Turn off the AC input breaker and open the front panel.
WARNING: AC power is still present at the top terminals of the input
breaker. Stored DC power is still present on the power board and may
still exist at the output terminals.
Move the “Vout-Vbatt” jumper to the Vout position. This alters sensing for the Under Voltage alarm
setup. Close the front panel. Adjust the under voltage control to the minimum setting. Turn the unit
“on”.
