DeviceNet Interface for Series 75 Electric Valve Actuator
FCD WCAIM2068-00
Each input is used to monitor either a mechanical switch or an
AC/DC two-wire NAMUR sensor. These switches have been factory
set to indicate full CW and full CCW position.
The DeviceNet circuit board has six LEDs:
a. Two LEDs for DeviceNet MNS bus activity, as required by the
ODVA (Open DeviceNet Vendors Association) Specification (see
Supplement 2: N0457-14142) (green/red) D1 & D2
b. Red LED to monitor CW limit switch D3
c. Green LED to monitor CCW limit switch D5
d. Yellow LED to monitor coil power D4
e. Orange LED to monitor solenoid coil continuity D6
The motors are powered from a separate power source (not the
DeviceNet cable).
The Access/DeviceNet Circuit Board meets the requirements of the
ODVA Specification. It is a Group 2 slave device, which operates as
a slave device on the DeviceNet network. It supports Explicit, Polled,
Change of State and Cyclic I/O Messages of the predefined master/
slave connection set. It does not support the Explicit Unconnected
Message Manager (UCMM).
The Access/DeviceNet Circuit Board has one byte of input (con-
sumed) data and eleven bytes of output (produced) data. In the input
byte, bits 0–4 are not used, bit 5 is used to control the CW direc-
tion, bit 6 is used to control the CCW direction and bit 7 is used to
reset the maintenance counter. Of the output bytes, byte 1 is used
to monitor the switch and slave relays status of the unit, with bit 0
used to monitor switch 3 CW position, bit 1 used to monitor switch
4 CCW position, bit 2 used to monitor switch 3 (not used in this
application), bit 3 used to monitor CCW slave relay and bit 4 used
to monitor CW slave relay. Bits 5–7 are not used. Of the remaining
bytes, bytes 2–5 make up the maintenance counter, bytes 6–9 make
up the cumulative counter.
2 Installation to Worcester
Controls/McCanna Valves
A. Attach mounting bracket to actuator using four cap screws and
Iockwashers, provided in mounting kit, and tighten securely.
For small size top-mount style valves, attach bracket such that
bracket nameplate is on the side of valve.
B. Attaching bracket/actuator assembly to valve:
NOTE: If cross-line mounting of actuator is desired, note the
following:
Mount the actuator with conduit hole perpendicular to the flow
axis (centerline) of the valve and reverse the open/close decals.
For diverter and 3-way valves with V1 porting, and for CPT
valves, also see Section 3, paragraph D, for cam and limit switch
adjustments to facilitate cross-line mounting operation.
a
CAUTION: Ball valves can trap pressurized media in the cav-
ity. If it is necessary either to remove any valve body bolts or
stem nuts, or to remove valve from the line, and if the valve
is or has been in operation, make sure there is no pressure
to or in the valve and operate the valve one full cycle.
1. Valve Models Top Mount 44 (¼"–2"), 45 (2½"–6"), 51/52
(½"–10"), 151/301 (3"–6"), Top Mount 59 (¼"–4"), WK70 & H71
(½"–2"), 818/828 (2"–8"), 82/83 (½"–10"), and 94 (1½"–6"):
NOTE: For above-listed valves, it is not necessary to remove any
valve body bolts or remove valve from line in order to mount
actuator.
a. Close valve. For valves ¼"–2", the valve is closed when flats
on valve stem are perpendicular to the line of flow; for valves
3" and larger, where the valve stem is square, the indicator
line on top of stem will be perpendicular to the line of flow
or check ball position for closure.
b. If any valve information is marked on stop plate or handle, it
will be necessary to transfer this information to the bracket
nameplate.
For Series Top Mount style valves 44 (¼"–2"), WK70
(¼"–2"), 59 (¼"–1½"), H71 (½"–1½"), and for valves with
high cycle stem packing as standard (51/52 (½"–2") and
82/83 (½"–1½"): Remove handle nut, Iockwasher, handle,
separate stop plate (if any), retaining nut and stop pin(s).
Add the two additional Belleville washers with their larger
diameter sides touching each other. Add the self-locking nut
to the stem and tighten while holding the stem flats with
wrench. Tighten until Belleville washers are flat; the nut will
“bottom,” and then back nut off

of a turn. The two addi-
tional Belleville washers and the self-locking nut are included
in the mounting kit.
a
CAUTION: The self-locking stem nut is difficult to
tighten, and must fully flatten Belleville washers
before backing off.
For 2" 59, H71,82/83, and 2½" 45, 82/83 Series valves
and valves 3" and larger with square stem, remove handle
assembly (if any), retaining nut, stop and stop screws.
Replace with valve stem spacer, or, if valve has graphite
stem packing, with two Belleville washers—except 8", 10"
82/83 and 10" 51/52—and replace retaining nut.
NOTE: Belleville washers are installed with larger diameters
touching each other. Using a wrench to prevent stem from turn-
ing, tighten retaining nut until stem packing is fully compressed
(or until Bellevilles, if used, are fully flattened), then back off nut
