ALM 1, 2, 3 can be output to alarm output 1, 2, 3, or changed with the ad-
vanced function setting level.
• The relay specifications are as follows:
CT Inputs • When the HB alarm or the HS alarm is to be used with the E5CZ-@2M@@
with E53-CZH03 or E53-CZHB, connect a current transformer (CT1)
across terminals 14 and 15 (no polarity).
• When the HB alarm or the HS alarm is to be used with the E5AZ/EZ-
@3H@@@, connect a current transformer (CT1) across terminals 14 and
15 (no polarity).
Event Inputs • When event inputs are to be used with the following models, connect to
terminals 11 to 13. Option unit with two event inputs is required to be
mounted.
• Use event inputs under the following conditions:
• The outflow current is approximately 7 mA.
Polarities during no-contact input are as follows:
