Control Outputs
The relay contacts provided in SLM102 are rated for 3A @ 230VAC. They are also
protected by snubbers against fast voltage transients which occur when inductive
loads are switched off. Thus, the following points are to be taken care of when using
these relay contacts:
1. Use 230VAC coils only in the contactors. DO NOT use 440V AC coils.
2. DO NOT switch small loads like electronic Hooters, small relays with 230VAC
coils etc. directly from the relay contact of SLM102. If done so, the small
leakage current from the snubbers will not allow these loads to be switched off
fully. Thus, the electronic hooters will give a low hum continuously, and the
small relays will switch on but not switch off. Use these relay contacts to
switch an Auxiliary contactor and put the load on the contactor contacts.
Alarm Action
Considering two alarm relays with previous section, ”Setting Four Alarm Relays,
Alarm On, Alarm Value and Alarm Hysteresis” in Programming Mode, user can
configure for a desired parameter for alarm control action such as shown below.
