Adept Cobra PLC600/PLC800 Robot User’s Guide, Rev C 141
7.5 Installing Robot Solenoid Kit
Introduction
This procedure describes how to mount the 24V solenoid option kit on an Adept Cobra
PLC robot. The solenoid kit is available as Adept P/N 02853-000.
The robot has been prewired to accommodate a bank of two 24 VDC solenoid valves.
Power for the internal mounting is accessible via a connector mounted inside the outer
link cover (see Figure 7-4 on page 142). The signals actuating the valves are directly
switchable from the PLC. Refer to Chapter 6 for register information. The Adept-supplied
solenoids each draw a nominal 75 mA from 24 VDC.
The solenoid valve assembly consists of two independent valves (Valve #1 and Valve #2)
on a common manifold. The manifold supplies air at the user’s line pressure (28 psi
(0.19 MPa) minimum to 114 psi (0.786 MPa) maximum). Each valve has two output ports,
A and B. The output ports are arranged so that when Port A is pressurized, Port B is not
pressurized. Conversely, when Port B is pressurized, Port A is not. In the Adept Cobra
PLC robots, the air lines from Port A on each valve are plugged at the factory (at the
solenoid assembly).
The Solenoid Kit for the Adept Cobra PLC robot is available through Adept. Contact your
Adept Sales Representative for current price and availability.
The Solenoid Kit for the Adept Cobra s-series robot is available through Adept. Contact
your Adept Sales Representative for current price and availability.
Tools Required
• Assorted Allen drivers
•Tie-wraps
• Pair of diagonal wire cutters
• Solenoid Valve upgrade Kit (Adept P/N 02853-000)
Procedure
1. Turn off all power to the robot.
2. Remove two screws on the Cobra PLC 600 (three screws on Cobra PLC 800) on
each side of the outer link cover. Remove two screws on top and remove the
cover.
3. Connect the Internal Solenoid Valve Cable assembly to the Solenoid Manifold
assembly, by plugging the SOL 1 connector into Valve 1 and SOL 2 into Valve 2.
