4. With assembly complete to this point, it is convenient to make
conduit connections and bring wiring through enclosure. The
power supply to the solenoid coil is 3 watts. Required amperage
is shown below. It should be noted that the successful use of this
device in hazardous, wet, or other detrimental environments
depends on proper conduit construction techniques.
Voltage Holding Amps*
24 VAC 50/60 Hz .13
120 VAC 50/60 Hz .025
240 VAC 50/60 Hz .013
12 VDC .25
24 VDC .13
*Inrush is 80% greater than holding values on AC solenoids.
5. When the switch (sensor) package is assembled, one of the
probes will make contact with the switch (sensor) button. Simply
press the switch (sensor) package until the mounting screws can
be engaged. Tighten mounting screws until bracket is secure.
6. Switches (sensors) have been factory adjusted, but should be
rechecked after installation. Adjustment is as follows:
A. Limit Switches using PC Board and LEDs (24 VDC; 24, 120
VAC):
With actuator mounted in “standard” fail-closed mounting
configuration (see Step 1) and wired per appropriate wiring
diagram, set actuator in full-closed position, CW limit of
rotation, with the adjustment screw near its loose limit. Adjust
closed position switch SW-2 (see Wiring Diagram) by
tightening the adjustment screw until red LED turns on. Then
for SPDT switch tighten adjustment screw one additional turn.
For DPDT switch tighten adjustment screw additional 1 /
4
turn
only.
With air supplied to actuator, energize the solenoid to change
actuator to its full-open position, CCW limit of rotation. The
yellow and orange LEDs should be lit indicating coil voltage
and coil continuity, respectively. Adjust the open position
switch, SW-1 in the same manner as the closed position
switch until the green LED turns on. Then for SPDT switch
tighten adjustment screw one additional turn. For DPDT
switch tighten adjustment screw additional
1 /
4
turn only. When
the solenoid is de-energized, the actuator will return to its
full-closed position. The yellow, orange and green LEDs will
turn off indicating solenoid de-energized and actuator no
longer in full open position and the red LED will turn on
indicating the actuator is in the full-closed position.
For fail-open mounting configuration, wire actuator per
appropriate wiring diagram, set actuator in full-open position,
CW limit of rotation, with adjustment screw near its loose
limit. Adjust open position switch SW-2, by tightening the
adjustment screw until the green LED turns on. Then for
SPDT switch, tighten adjustment screw one additional turn.
For DPDT switch tighten adjustment screw additional
1 /
4
turn
only.
With air supplied to actuator, energize the solenoid to change
actuator to its full-closed position, CCW limit of rotation. The
yellow and orange LEDs should be lit indicating power to the
coil and coil continuity, respectively. Adjust the closed
position switch, SW-1 in the same manner as the open
position switch until the red LED turns on. Then for SPDT
switch, tighten adjustment screw one additional turn. For
DPDT switch, tighten adjustment screw additional
1 /
4
turn only.
When the solenoid is de-energized, the actuator will return to
its full-open position. The yellow, orange and red LEDs will
turn off indicating solenoid de-energized and actuator no
longer in full closed position and the green LED will turn on
indicating the actuator is in the full open position.
NOTES: For DPDT switches, customer must wire directly to the
outside set of terminals of each switch. The wires on the circuit board
will be wired to the switches by the factory using the inside set of
terminals of each switch.
If actuator is mounted in any other than “standard” configuration,
consult Step 1 of Installation Instructions to insure proper orientation
of probes and switches (sensors).
B. Limit Switches using PC Board and switch indication LEDs
only. (240 VAC dual-voltage boards or 24 VDC; 24, 120 VAC
units without a solenoid):
With actuator mounted in “standard” fail-closed mounting
configuration (see Step 1) and wired per appropriate wiring
diagram, set actuator in full-closed position, CW limit of
rotation, with the adjustment screw near its loose limit. Adjust
closed position switch SW-2 (see Wiring Diagram) by
tightening the adjustment screw until red LED turns on. Then
for SPDT switch tighten adjustment screw one additional turn.
For DPDT switch tighten adjustment screw additional 1 /
4
turn
only.
With air supplied to actuator, energize the solenoid (if
applicable) to change actuator to its full-open position, CCW
limit of rotation. Adjust the open position switch, SW-1 in the
same manner as the closed position switch until the green
LED turns on. Then for SPDT switch tighten adjustment screw
one additional turn. For DPDT switch tighten adjustment
screw additional
1 /
4
turn only. When the solenoid is de-
energized or the air supply is off, the actuator will return to its
full-closed position. The actuator is no longer in full-open
position and the red LED will turn on indicating the actuator is
in the full-closed position.
For fail-open mounting configuration, wire actuator per
appropriate wiring diagram, set actuator in full-open position,
CW limit of rotation, with adjustment screw near its loose
limit. Adjust open position switch SW-2, by tightening the
adjustment screw until the green LED turns on. Then for
SPDT switch, tighten adjustment screw one additional turn.
For DPDT switch tighten adjustment screw additional
1 /
4
turn
only.
With air supplied to actuator, energize the solenoid (if
applicable) to change actuator to its full-closed position, CCW
limit of rotation. The yellow and orange LEDs should be lit
