Load On/Off; Protection Features - Chroma 63200 Series Operation & Programming Manual

3.10 Load On/Off

A module's input can be toggled on/off through the blue LOAD ON/OFF key on the front panel,
or the remote control.
Turning off the load does not affect the programmed setting. The load will return to the
previous programmed values when the Load is turned on again.

3.11 Protection Features

The load includes the protection features: Over power, Over temperature, Fan fail, and
Abnormal Alarms for Reverse Voltage and Over Voltage.
The appropriate bits in the Load status registers are set when any of the protection features or
alarm listed above is active. The Load's buzzer will beep to inform you till protection or alarm
status is reset. When any of the protection or alarm occurs, the Load input will turn off.

Over voltage
The over voltage alarm circuit is set at a level slightly above the voltage range specified in
the Load specification. The over voltage status register bit is set when the OV condition
occurs and will remain set till it is reset. The Load will appear OVP as below when over
voltage alarm occurs.

Over current
When Load is operating in CR or CV mode, it is possible to attempt loading current more
than it is rated for. The limit level of current is set at a level slightly above the current of
the Load. The over current status register bit is set when the OC condition occurs, and
will remain set till it is reset. The Load will appear as below when over current protection
occurs.

Over power
The over power protection circuit is set at a level slightly above the power range specified
in the Load specifications. The over power status register bit is set when the OP
condition occurs, and will remain set till it is reset. The Load will appear as below when
over power protection occurs. This protection will be activated also if the power exceeds
the maximum surge load capability mentioned in section 3.5.5.
The on/off change for input is done according to the slew rate.
