14.2 Outlet Control
The outlet can be energised by local or remote operation depending on the “Remote Start” option. The
selection is “Yes” or “No” (Level 9, Position 14).
14.2.1 RTU Mode
If “Yes” is selected the relay ignores the local start input thus allowing operation of the outlet from the
remote machine.
Both the remote and local stop buttons will turn off the outlet.
If “No” is selected the local start/stop buttons control the outlet. The Remote Termination Unit’s
start, stop and PTC terminals must be bridged to energise the outlet.
Stop/Start functions are operational only. Emergency stops must be
wired directly into the pilot circuit.
14.2.2 Remote Operation in Diode Mode
In this mode the stop/start station is connected in the pilot (see Typical Connection Diagram IPDE001
in Appendix A – Drawings). The pilot has a hysteresis of 100 ohms. This is to allow a 100 ohm resistor
to be connected across the start button. The hysteresis is linked to the main contactor input (MCI). If
MCI is open, then the earth continuity will trip at 45 ohms. If the MCI is closed, the earth continuity trips
at 145 ohms.
It is also necessary to bridge the local start button or start input on the relay, on the outlet controlled by
this method.
Both the remote and local stop buttons will turn off the outlet.
Stop/Start functions are operational only. Emergency stops must be
wired directly into the pilot circuit.
