Instruction manual

indicates for which all CHANNELS the LIMIT has to be SET. The

same data will be set on all the specified CHANNEL(S). Once

this limit is set, from that point onwards the output voltage can

not be set to higher values than this. If you try to set higher value

using SOURce:VOLTage command, the “ Execution error “ will

be generated. At the same time the LIMITS can not be set to a

value, which is more than the MAXimum ratings of the

CHANNEL(S). Also the read value of Voltage is checked with the

Soft Limit Voltage value all the time and if the reading exceeds

the Channel will be TRIPPed, giving the reason for TRIP as S/W

OVP TRIP.

For example to set Limit of 30.80 Volts on Channel 2, send the

command as :

SOURce:VOLTage:LIMit 30.80(@2)

VOLT:LIM 3.08 E+1(@2)

5. Command : [SOURce:]VOLTage:PROTection<SP>

<NR.DATA><Channel_list>

Description : Set Over Voltage Protection Limit for that Channel(s).

Function : This command sets the Over Voltage Protection Limit for that

CHANNEL of the Power Supply output with the <NR.DATA> given

in the command in Volts. The input VOLTAGE data is in Numeric

Data format. The <Channel_list> above, indicates for which all

CHANNELS the OVP has to be SET. The same data will be set

on all the specified CHANNEL(S). If no such <Channel_list> is

provided the PROTection command will always SET to channel

1 OVP. Once this OVP limit is set on a channel, any time if the

actual Output Voltage of the channel exceeds the OVP limit, the

CHANNEL(S) will be ‘TRIPed’. I.e. the OVP operates to protect

the channel and the O/P voltage will be made zero and the OUT-

PUT ON/OFF relay will be switched OFF.

For example to set OVP of 31.50 V on Channel 2, send the com-

mand as :

SOURce:VOLTage:PROTection 31.50(@2)
