Instruction & Operating Manual For
About DeviceNet
DeviceNet is an open network standard originally developed by Allen-Bradley and based on a broadcastoriented, communications protocol - the Controller Area Network (CAN). The CAN protocol was originally
developed by BOSCH the european automotive market for replacing expensive, wire harnesses with a lowcost network.
In 1995 Allen-Bradley released the protocol to the open DeviceNet Vendors Association (ODVA). ODVA
oversees the development of the DeviceNet specification and the conformance testing of Devicenet products.
ODVA is open to any manufacturer or user of this protocal with a worlwide membership of approximately
300 companies.
DeviceNet is a simple networking solution that reduces the cost and time required to install and wire
industrial automation devices. A single DeviceNet Intellis System will accomodate up to 63 valves and 1008
discrete I/O points. Although a simple system to design and implement, DeviceNet has the capability to interconnect complex as well as simple devices to the same network, easily accomodating both analog and discrete
I/O.
Westlock Intellis DeviceNet Module EL-40092
The EL-40092 module is a 4 input, two output network monitor. Inputs 0 and 1 are internal Hall effect
sensors that are activated by the field of a magnet (south pole). Inputs 2 and 3 are active high/low (activated
by pulling the input up to +24V or activated by pulling the input down to ground). The outputs are open drain
active low FETs, fused (solid state resettable) at 0.2A with diode protection to 24Vdc. For current consumption see Table 1, page 9. Minimum power supply input voltage is 19Vdc to insure proper solenoid operation.
Connection to the network is via DeviceNet specific cable. There are both Round and Flat Media. Refer
to the Cabling Information section, page 6 of this document for more information. See also Allen-Bradley
document “DeviceNet Cable System”’ (Cat. No. DN-6.72) for a detailed treatment of this topic.
For data exchange to occur, each network monitor connected to the DeviceNet network must be programmed with a unique address, numbered between 0 and 63 and all nodes must be set to the same Baud rate
as the scanner. This may be accomplished via setting the DIP switch, S1, on the electronics module. Refer to
Tables 4, 5 and 5.1 page 10.
The address and Baud rate may also be set via explicit Messaging if positions 7 and 8 on S1 are set to the
“On” position.
It is possible to exchange or add slaves during normal operation without interfering with communications
to other nodes.
The Westlock Controls Corp. DeviceNet Module, EL-40092, operates as a GROUP 2 Only Slave on a
DeviceNet network. The unit supports Explicit Messages and Polled I/O Messages of the Predefined Master/
Slave Connection Set. The device does not support the Explicit Unconnected Message Manager (UCMM).
Refer to the Specification Overview, page 8 for a summary of features.

Installation Instructions
IMPORTANT: If the valve monitor is in the field already mounted on an actuator and valve,
please follow the field wiring instructions on the next page.
Warning: The valve monitor should always be handled with care when the cover is removed and
wired to an electrical power source.
1. Attach the proper mounting bracket and adapter to the valve monitor housing with the hardware
provided.
2. Operate the actuator to full closed position.
3. Attach the valve monitor and mounting bracket to the actuator.
4. Note graphic display of the Beacon and circle one of the coinciding drawings shown below.

Switch Adjustment
Note: Switches are factory set. If you need to adjust for any reason follow instructions below.
1. To set switches, lift bottom cam and turn until switch is activated and then release. Spring will
push cam back onto the splined shaft. Operate the actuator to the opposite extreme, push down
on the top cam and turn until the open switch is activated.

Wiring Instructions
1. Wiring options for 7644 & 7679/D-7679 ME or XE are shown in Fig. 1-3 below. The proper wiring
diagram for your unit is shown on the inside of the 7679ME or XE covers.
2. All wiring must be in accordance with National Electrical Code (ANSI-NFPA-70) for area classifications. The valve monitors are approved as explosionproof for Class I, Division 1, Groups C and D; nonincendive for Class I, Division 2, Groups A,B,C and D; dust-ignitionproof for Class II/III, Division 1,
Groups E,F and G hazardous (classified) locations; indoor/outdoor (NEMA type 4, 4X).
Always check the nameplate to make sure the agency approval ratings coincide with the
application.
Caution: To Prevent Ignition of Hazardous Atmospheres, Replace Cover Before Actuating the
Electrical Circuits. Keep Cover Tightly Closed When in Operation.
