Wiring the Relay Output
The RocketLinx ES8108/ES8108F have a built-in alarm-relay for port link and power events notifications. The relay contacts
are normally open and remain open when there is no failure event. The relay contacts will close when there is a failure event to
notify.
The failure events are selectable and enabled using the DIP switch on the ES8108/ES8108F. The relay contacts of RocketLinx
ES8108/ES8108F are rated for a maximum of 1A at 24VDC.
Wiring the alarm relay output is the same as wiring power inputs in
Connecting the Power and Ground
.
1. Insert positive and negative wires into V+ and V-.
2. Tighten the wire-clamp screws to prevent the wires from coming loose.
Enabling the Event Alarm
You can use this subsection to configure and enable the event alarm to alert maintenance engineers once a system event has
occurred. The RocketLinx ES8108/ES8108F is equipped with one dry relay output for port link failure or power failure.
On the bottom of the ES8108/ES8108F, there is one 9-pin DIP switch for alarm control. If you connect the alarm (
Wiring the
Relay Output
on Page 12) and set the DIP switch of the intended Alarm to
ON
, the relay output forms a short circuit if an alarm
occurs.
Use this table to set the DIP switch for the relay output alarm.
