Notes
1.
A minimum wire of 14 AWG (2.5 mm
2
) should be used
between the 24 Vdc control power supply and the
control terminal block.
2.
See Using an Auxiliary Relay section below if it is desired
to use a relay instead of an indicating lamp for terminals
13, 14, 95, 96 and 98.
3.
120 Vac may be applied to terminals 13, 14, 95, 96,
and 98.
4.
Add ferrite, Fair-Rite #0446176451 to DC Power Leads
and Control I/O Leads (all through one ferrite) at S811+.
5.
Functionality of terminals 1, 2, 3, and 4 are shown in the
default configuration. These terminals are programmable
for other functions. In a 3-wire control system, at least
one terminal must be assigned to a Start command
(RUN1) signal.
6.
Auxiliary relays: 3 amps at 120 Vac or 24 Vdc, 10 amps
max. (resistive) switching.
