Over Voltage Protection)/ U.v.l(Under Voltage Limitation) - Matsusada Precision VOL Series Instruction Manual

４-４ O.V.P(Over Voltage Protection)/ U.V.L(Under Voltage Limitation)
・ When pressing the OVP/UVL switch the set OVP value on voltage meter and set UVL value on current
meter are indicated. .
・ On O.V.P/U.V.L setting display O.V.P/U.V.L value can be set by turning voltage/current setting dial.
・ When set the OVP/UVL value to be "0", it is possible to cancel the protection.
[O.V.P]
・ When the output voltage gets low than the set OVP voltage value, OVP function shall cut off the output.
・ When OVP is effective display shows "OVP/E01" and cut off the output(OUPUT LED light off)
・ Press OUTPUT ON/OFF switch or turn OFF the LS(remote switch) resets the cut off status.(display
shall return to previous display from "OVP/E01")
・ To resume the output turn on the output switch or turn ON the LS (remote switch). (after adjusting
output voltage of O.V.P voltage value) (OUTPUT LED light on)
[U.V.L]
・ When the output voltage gets lower than the set UVL voltage value, UVL function shall cut off the
output.
・ When UVL is effective display shows "UVL/E08" and cut off the output(OUPUT LED light off)
・ Press OUTPUT ON/OFF switch or turn OFF the LS(remote switch) to reset the cut off status.(display
shall return to previous condition from "UVL/E08")
・ To resume the output turn on the output switch or turn ON the LS (remote switch). (after adjusting
output voltage of U.V.L voltage value) (OUTPUT LED light on)
display for about 2 seconds.
