¡
When a coil load is connected in the same control circuit as the ETR, surge absorbers are required to absorb the surge v
oltage
(electromotiv
e f
orce).
¡
OCR alar
m (AL)
The contact output of the OCR alar
m (Standard type AL) is the one-pulse output (30-50 ms).
For this reason, this output needs self-holding circuit.
¡
In case of type P3 or P4, the alar
m contact output rela
y is high sensitiv
e rela
y.
Theref
ore ma
y occur a chatter
ing noise (appro
ximately
1ms) b
y ON/OFF oper
ation of the break
er
. Please adopt a time constant filter of se
ver
al ms
, or doub
le-reading (sampling), or the lik
e.
¡
Closing coil (CC)
Do not use AXb contact f
or a cut-off s
witch, because pumping pre
vention is not perf
or
med.
¡
Under v
oltage tr
ip de
vice (UVT)
As the pushb
utton s
witch f
or tr
ipping, use a s
witch ha
ving a contact capacity of 150
V DC
, 0.5 A or more
.
A shor
t-circuiting bar has been fitted to the tr
ip ter
minals
. Bef
ore using the tr
ip ter
minals
, remo
ve the bar
.
Disconnect the v
oltage input wires dur
ing dielectr
ic testing of main circuit.
¡
From some ter
minals are polar
ized, the wir
ing should be done correctly as to the polar
ity sho
wn in the wir
ing diag
ram when the
control v
oltage is DC
. A
uxiliar
y s
witch (AX) Standard type has no polar
ity
.
¡
Reset Circuit
As the pushb
utton s
witch f
or resetting the tr
ip indicator
, use a s
witch ha
ving a contact capacity of 15V DC
, 10mA or more
.
