Procedure for Setting the End-of-Charge” Voltage:
Setting the end-of-charge voltage shall be done in a laboratory. The
output shall be open (not loaded, no capacitor needed). The output
voltage (end-of-charge voltage) shall be measured with a digital
voltmeter.
Factory setting of the end-of-charge voltage is 410Vdc and the OVP
level is 10V higher. Changing of these values can be done
according to the following examples:
Example 1:
Setting the end-of-charge voltage to 420V and OVP to 430V
Step 1: Push the “OVP disable / enable” button to disable the OVP.
The red LED will start and keep flashing for two minutes. For this
period of time the end-of-charge voltage can be set without
triggering the OVP. Ensure that the unit is not in OVP mode before
starting with step 1.
Step 2: Set the end-of-charge voltage to 420V
Step 3: Push the “OVP disable / enable” button again to set the
OVP voltage 10V higher than the end-of-charge voltage(= 430Vdc).
Red LED will go off.
 done
Example 2:
Setting the end-of-charge voltage to 430V and OVP to 450V
Step 1: Push the “OVP disable / enable” button to disable the OVP.
The red LED will start and keep flashing for two minutes. For this
period of time the end-of-charge voltage can be set without
triggering the OVP.
Step 2: Set the end-of-charge voltage to 440V
Step 3: Push the “OVP disable / enable” button again to set the
OVP voltage 10V higher than the end-of-charge voltage(= 450Vdc).
Red LED will go off.
Step 4: Set the end-of-charge voltage to 430V (without pushing the
button)
 done
