Overtemperature Protection (OTP)
There is an overtemperature protection circuit, which will turn off the input if the internal
temperature exceeds safe limits. When the electronic load’s internal circuit temperature is over
85C, the load will enable OTP. Input will automatically be turned off and the VFD will display
OTP. At the same time the OT and PS bits in the status register will be set and remain until they
are reset.
Operations to Clear the OTP State
When the electronic load temperature has dropped below the protection point, press any key
on the front panel or remotely send command PROTection:CLEar. The OTP displayed on the
front panel will turn off and the electronic load exits OTP protection state.
Reverse Voltage Protection (LRV/RRV)
This function protects the electronic load in case the input DC voltage lines are connected with
the wrong polarity. When a reverse voltage (LRV local reverse voltage, RRV remote reverse
voltage) connection condition is detected, the input will immediately turn off, the buzzer will
alarm the user, and the status register’s reverse voltage (LRV/RRV) and VF bits will be set. The
load will display LRV/RRV until they are reset.
In this condition, the VF pin will output a low level.
Operations to Clear the Reverse Voltage State
Check whether the connection is reversed. If so, disconnect the device to be measured and the
reverse voltage state will be cleared.
