Chapter 6: Optional Equipment Installation

NOTE:The cover on the outer link must be removed for maintenance (lubrication),

so keep this in mind when mounting any external equipment to the outer link

cover.

6.6 Installing the Robot Solenoid Kit

This procedure describes how to mount the 24 V Robot Solenoid option on Adept Cobra

ePLC600 and ePLC800 robots. The kit is available as Adept P/N 02853-000.

The robot has been pre-wired 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 6-8). The signals actuating the valves are set in the eAIB, by default, to 3001 to 3004.

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: minimum 28 psi

(0.19MPa), to maximum 114 psi (0.786 MPa). 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 ePLC 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 ePLC600/800 robots is available through Adept. Contact

your Adept Sales Representative for current price and availability.

Procedure

Turn off all power to the robot.

Remove two screws on ePLC600 (three screws on ePLC800) on each side of the outer

link cover. Remove two screws on top and remove the cover.

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.
