Section 1 General Introduction
1.1 General Description
The Athena “S” Series Solid State Staging Controls
Provide pilot duty sequencing of multiple loads up to
18 stages.
SU - Up-Down Mode:
Adds stages in progression. Removes stages in
reverse order., the last stage ‘on’ being the first stage
‘off’ on load reductions. Blue Handle Cooling stages
provide automatic transfer to cooling. Starts with all
stages ‘off.’
Output capacity: 1 AMP per step (10 Amps inrush).
SC - Circular Mode:
Operates all heaters and contractors evenly. First
stage ‘on’ is first stage ‘off.’ Starts with all stages ‘off.’
Output capacity: 1 Amp per step (20 Amps inrush).

Section 2 Installation Instructions
2.1 Installation.
1. Carefully unpack instrument. Handle with care.
Inspect for shipping damage. Report and damage to
carrier immediately.
2. Pick a location for the controller where it will not be
subjected to excessive shock, vibration, dirt, moisture
or oil. The ambient temperature of the area should
be between 30º and 130ºF (-1.1º to 54.4º C).
3. Mount the controller
with four 8-32 x
” screws. The
controllers are not
position sensitive
and can be mounted
in any plane.
4. Consult the wiring
diagram on the next
page. Standard
units require
120 V 50/60 Hz.
5. Be certain that
power is off. Then
connect power wires
to .250 push-on
terminals marked X1
and X3. If used on
a grounded system,
the X2 terminal should be grounded.
