Power Supply Function

Warm-up

Indicates the instrument

warm-up time. This time

is set to prevent the in-

strument from triggering

protection when the

voltage is rising. Be-

cause this transient

condition should not be

considered as an

undervoltage fault and

there is no need to trig-

ger protection.

Protection delay time,

see Protection Delay.

Protection Delay

You can specify an OCP/OVP/OPP/UCP/UVP delay to prevent momentary out-

put settings and status changes from tripping the protection. In most cases

these momentary conditions would not be considered an protection fault, and

having an OCP/OVP/OPP/UCP/UVP condition disable the output when they oc-

cur would be a nuisance. Specifying an protection delay (Delay) can ignore

these momentary changes during the specified delay period. Once the delay

time has expired and the protection limit condition persists, the output will shut

down.

Protection Prompt

When the instrument enters the protection state, the buzzer sounds (if Beep

menu item is set as default state On), the VFD status indicators Prot and Off

are lit, and [On/Off] is turned off.

Although [On/Off] is turned off, there may be dangerous voltage

at the output electrodes. Do not touch the wiring cable or the

electrode terminals.

When protection is generated, the VFD screen displays the following

information:
