ENABLING / DISABLING OVER VOLTAGE PROTECTION
The user can enable or disable the OVP circuit by pressing the "OVP ON/OFF (2)" key. When it is
enabled the OVP enunciator is on.
When the VFD displays “OVER VOLTAGE”, the over voltage protection circuit has been activated and
the output is disabled. To reset, press the "CLEAR (RESET)" key. To turn the output on again, press the
"OUT ON/OFF (1)” key.
<NOTES:>
1. Remote sensing, take into consideration the voltage drop across the load leads since the threshold
measurement is taken a
t the output.
2. In inductive load applications, a high-surge voltage would enable the OVP circuit and disable the
output.
3. Also note the programming resolution and programming accuracy specifications
4. When the OVP cir
cuit is disabled, the threshold voltage becomes invalid.
OVER CURRENT PROTECTION
The power supply has an over current protection (OCP) feature to guard the supply against current
overdrawn. If the OCP feature is enabled and the supply switches to CC mode, the OCP circuit is triggered
and the output is disabled. The OCP threshold is set by the value of the current limit.
