CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
7 – 8 with a multimeter.
3) Input: Check voltage across the terminal 5 (+) – 6 (–)
with a voltmeter to show 0V at 0% potentiometer input
and the same voltage as that across 4 (+) – 6 (–) at 100%
input.
4) Alarm operations: Check the alarm operations referring
to the figure below.
5) Output load: Check that the output load is 380V
AC/120VA or 125V DC/30W (380V AC/600VA or 125V
DC/150W for dual alarm, Output Code 5) at the maxi
-
mum. For maximum relay life with inductive load, ex-
ternal protection is recommended.
