4 10, 15, 20 Access I 39 Acutators with AS Interface WCAIM2041
• maximum supply current including activated solenoid
• ≤125 mA
• operating temperature -25 to +70° Celsius
• storing temperature -25 to +85° Celsius
• printed circuit board dimensions (51 x 51 mm)
• connection of two switches/NAMUR proximity sensors
with wires
• connection of one solenoid with wires
• connection of AS-Interface with wires
3. Indication:
• switching states of the switch/NAMUR proximity
sensor – inputs:
A = LED (H1, red), lights if the switch/NAMUR
proximity sensor 2 is closed/on
B = LED (H2, green), lights if the switch/NAMUR
proximity sensor 1 is closed/on
• one LED (H4, yellow) for the switching state of the
solenoid, the LED lights if the solenoid is switched on
• one LED (H3, orange) for short-circuit and line break
monitoring of the solenoid output, the LED lights if there is
neither a short-circuit nor a line break on the solenoid
output
4. Specification of the Switch/NAMUR proximity sensor inputs:
• Supply: 8 V, 8 mA for each switch/sensor (NAMUR -
specification)
• No line break and short-circuit monitoring
• These inputs are indicated via AS-Interface data bit D2
(Switch/Sensor 2) and D3 (Switch/Sensor 1)
5. Specification of the valve output:
• output voltage: 24-30 VDC (depending on the voltage of the
ASi-line and the load current of the solenoid)
• power consumption of the solenoid: max. 3 W / 24 V
• the solenoid is switched on via the AS-Interface data bit D0
(D0=1: solenoid is switched on)
• line break and short-circuit monitoring:
These failures are indicated via AS-Interface data bit D1
D1 = 0: line break or short-circuit at the solenoid output
D1 = 1: no line break and no short-circuit, solenoid is
switched on.
Line break and short-circuit at the solenoid output are only
monitored when the solenoid is switched on.
C. Electrical Connection
1. The “standard” mounting configuration of the 39 actuator to
the valve is fail-closed. In this configuration, SW-2, as
described in C.3 and in the wiring diagram, will give indication
when the actuator is in the closed position and the red LED
will be on. SW-1 gives indication of the open position and
green LED will be on. Actuator shaft rotation will vary,
depending on which fail-closed mounting is used. (Refer to
appropriate wiring diagram in Section C.4.).
NOTE: The rotation of the actuator shaft, CW (clockwise) or
CCW (counter-clockwise), is determined when viewing the
actuator from the nameplate side of the actuator while being
able to read the nameplate from left to right.
2. Fail-open mounting configuration may be obtained by either
inverting the actuator, using inline coupling or mounting the
actuator cross-line. In these cases SW-1 and SW-2 indication
will be reversed from the above but actuator shaft rotation will
vary, depending on which fail-open mounting is used. Wiring
shall be done per the appropriate wiring diagram in Section
C.4. and adjustments per Section C.3.
3. Switches/Sensors (if installed) have been factory adjusted,
but should be rechecked after installation. Adjustment is
as follows:
a. With actuator mounted in standard “FAIL-CLOSED”
mounting configuration (see step 1) and wired per
appropriate wiring diagram, set actuator in the full closed
position, with the adjustment screw near its loose limit.
The Orange LED indicating solenoid coil continuity will be
lit. The Orange LED will remain lit as long as there is
power to the circuit board and there is no short circuit or
open circuit with the coil. However, it should be noted
that, if there is a short circuit or open circuit with the coil,
the Orange LED will only turn off when an attempt is
made to energize the coil. This also applies to the Input 1
(Bit 1) status. Adjust closed position switch or Namur
proximity sensor SW-2 (see wiring diagram) by tightening
the adjustment screw until red LED turns on. Then tighten
the adjustment screw one additional turn. With air
supplied to actuator, energize the solenoid and cycle valve
to full open position. The Yellow and Orange LEDs should
be lit indicating power to the coil and coil continuity,
respectively. Adjust the open position switch/sensor SW-1
in the same manner as the closed position switch/sensor
until the green LED turns on, then tighten the adjustment
screw one additional turn.
When the solenoid is de-energized, the actuator will
return to its full closed position. The Yellow and Green
LEDs will turn off indicating that the solenoid is de-
energized and the actuator is no longer in the full open
position and Red LED will turn on indicating that the
actuator is now in the full closed position.
b. For actuator mounted in fail-open mounting
configuration (see step 2) and wired per appropriate
wiring diagram, set actuator in the open position with
the adjustment screw near its loose limit. Adjust open
position switch or Namur proximity sensor SW-2 by
tightening the adjustment screw until the green LED
turns on, then tighten the adjustment screw one
additional turn. With air supplied to actuator, energize
the solenoid to change actuator to the full closed
