Over Current
When work in the CR or CC and CP mode, input current is ascending continuously,
the load current will be limited by a current limit circuit, Load will work in the over
current protection state , VFD display the information as CC.
When work in CV mode and transition mode and List mode, Input current exceeds the
current limit, Buzzer is mooing, VFD display the flashing current value.
Over Power
If the input power exceeds the power limit in the normal operation mode, Load will
work in the over power protection state. VFD displays the information as CW.
When work in transition mode and list mode, If the input power exceeds the power
limit. Buzzer is mooing, VFD display the flashing current value and voltage value.
Reverse Voltage
This feature protects the load module in case the input DC voltage lines are
connected with wrong polarity, if a reverse voltage condition is detected, Buzzer is
mooing. VFD display as following:
Over Temperature
If internal power components ‘s temperature exceeds safe limits (80? ), Over
temperature protection is on work . Load will turn off the input and Buzzer is mooing,
VFD display as following:
Remote Sense Function
When work in CV, CR and CP mode, if load consumes biggish current, it will cause
one depressed voltage in the connection line between tested machine and terminals
of Load. In order to assure testing precision, Load provides one remote testing
terminals in the rear panel, Users could test the output terminals voltage of tested
machine through it. Users should set the Load in REMOTE mode before using the
function.
