c.Solenoid Replacement

The SPS 4000 manifold has a calibration gas 1 (high calibration gas) solenoid (20, Figure 9-13)and a calibration gas 2 (low calibration gas) solenoid (13).

Disconnect and lock out power before working on any electrical components.

1.Turn off power to the system.

2.Shut off the calibration gases at the cylinders.

3.Remove screw (7) securing manifold cover lock (6) and remove the lock.

4.Remove manifold cover (14).

5.Remove two screws (11) attaching spacers (9) to manifold (5).

6.Being careful not to disconnect the board wiring, carefully lift the board and spacer assembly from manifold (5) and set aside. Do not lose O-rings (8) from the bottom of spacers (9).

7.Tag and unplug solenoid (13 or 20) leads from power supply board (18). Refer to Figure 9-14.Calibration gas 1 solenoid wires connect to connector J5, and calibration gas 2 solenoid wires connect to connector J4.

8.Remove the top nut of solenoid (13 or 20, Figure 9-13)securing the coil as- sembly and washer to the base. Re- move the coil assembly, including the leads, and washer. Place a 13/16 in. deep socket over the solenoid base and remove.

When installing a solenoid, do not over-tighten. Damage to the solenoid may occur.

9.Install the new solenoid base. Be careful not to overtighten. Install the new washer and coil assembly and se- cure with the top nut. Connect the leads to the proper connector on power supply board (18). Refer to Figure 9-14if necessary.

10.Carefully install the board and spacer assembly into manifold (5, Figure 9-13)by aligning spacers (9) with the mounting holes on the manifold and securing with screws (11). Ensure O-rings (8) are installed between the spacers and the manifold surface.

11.Install manifold cover (14), and secure with manifold cover lock (6) and screw

(7).

12.Turn on the calibration gases at the cylinders.

d.Pressure Switch Replacement

Use the following procedure to replace pressure switch (12, Figure 9-13).

1.Turn off power to the system.

2.Shut off the calibration gases at the cylinders.

3.Remove screw (7) securing manifold cover lock (6) and remove the lock.

4.Remove manifold cover (14).

5.Remove two screws (11) attaching spacers (9) to manifold (5).

6.Being careful not to disconnect the board wiring, carefully lift the board and spacer assembly from manifold (5) and set aside. Do not lose O-rings (8) from the bottom of spacers (9).

7.Tag and remove the leads from pres- sure switch (12).

8.Place a 1-1/16 in. 6-point socket over pressure switch (12) and remove.
