9. FAULTS AND TROUBLE SHOOTING

9.1 OUP: Over Voltage Protection
This unit has a built-in tr acking over voltage p rotection fe ature. In the event of output voltage becoming

greater than the set value (see specified ra nge from specifications table), protection will be triggered and the
o utput p ower will be cut off and OUP warning appears as below.

To reset the warning, s witch off the unit and remove all loading.
Switch the unit back on again and it should resu me normal operation.
If this problem persists, please contact and consult with your agent.

9.2 OTP: Over Temperature Protection
There is a thermo sensor inside the unit to monitor and to prevent the unit to ge ts too hot inside. At OTP, there

is no outp ut and the following warning will a ppear on the LED display.

When you get this warning, switch off the unit and remove all loading.

Check your load and output setting. Allow the unit to cool down for at least 30 minutes.
Check if any of the ventilation is bl ocked, check enough cle arance around power supply.
Listen carefull y for the shor t wind noise from the cooling fan when you turn on the unit again.
I f you cannot hear thi s routine self te st wind noise on swit ch on, the fan is fa ult and do not use t he power

supply, contact your agent.

9.3 OLP: Over Load Protection

Normally the overload protection is sustained by the CC constant current mode.
When the CC mode fails and goes undetected, it may cause serious damage to your test piece or load.
The OLP is to minimize the extent of damage to your loads as power supplies do fail someday.
Switch off your power supply as soo n as you see t his warning as shown below.

To reset this warning, switch off the u nit and remove all loading.
Switch the unit back on a gain and d ouble check with caution.
If this problem cannot be fixed, please contact and consult with your agent.

HCS USB configuration for remote programming

This application note describes the procedure to configure the USB port for HCS remote programming application.
HCS remote programmable power supply with USB can connected to PC through USB cable.

USB to serial bridge design i s used . When connected to PC, it will be converted as COM port shown in the following
picture. e.g. COM3

If the COM port does not come up, please check if the USB driver has been probably installed.
The USB driver comes with HCS software CD. Make sure the CD has been load to computer first.
Then it can program as stand COM port.

The default COM port setting;
baud rate : 9600
Data bits : 8 bit
stop bit : 1
Parity : None
