Grounding

Installation (Model
249849)
The intrinsically safe flow control module (FC) is required to use flow control in your system. See F
1. Connect a 1/4 in. (6 mm) OD air supply line to the air inlet fitting of the flow control module (FC). Con­nect the other end of this line as follows:
a. Wall Mount Systems: Connect to the air mani-
fold at the rear of the wall mount fluid station.
b. RoboMix Systems: Install a 1/4 in. (6 mm) OD
tube tee at the air logic inlet of the RoboMix. Connect the flow control air line to one branch of the tee and the main air line to the other branch.
2. Connect a fluid line from the proportioner to the 1/8 npt(f) fluid inlet of the flow control module (FC).
3. Connect a fluid line from the 1/8 npt(f) fluid outlet of the flow control module (FC) to the spray gun inlet.
IG. 1.
Your system must be grounded. See the Grounding instructions in your ProMix Installation manual.
Ground all components in your system, as explained in your ProMix Installation manual.
Ground a remote fluid regulator (used with Model 24H989 only) by connection to a properly grounded fluid hose.

Before Servicing

NOTICE
To avoid damaging circuit board when servicing, wear Part No. 112190 grounding strap on wrist and ground appropriately.
1. Flush system and follow Pressure Relief Proce- dure in your ProMix Repair-Parts manual.
2. Close main air shutoff valve on air supply line and on ProMix.
3. Shut off power (0 position). F
4. Shut off power at main circuit breaker.

Servicing the Regulator and Pressure Sensor (Model 249849 only)

Regulator Service Kit 15G843 is available. Kit parts are marked with an asterisk, for example (602*). For best results, use all parts in the kit.
Sensor Service Kit 15G867 is available to service the pressure sensor only. Kit parts are marked with a sym­bol, for example (602‡). For best results, use all parts in the kit.
1. Follow Before Servicing, above.
2. Remove the four screws (605) and the nut (601) from the underside of the air plate (607). Separate the air plate and fluid plate. F
3. Unscrew the pressure sensor (620) from the fluid plate (606).
NOTE: If you are only replacing the pressure sensor kit 15G867, skip to step 6.

IG. 3: Power Off
5. Disconnect all air and fluid lines from the flow con­trol module.
6. Model 24H989 only: Disconnect all fluid lines from the pressure sensor fitting (626).
7. Disconnect the flow control cable from the flow con­trol harness (624). F
IG. 4 or FIG. 5.

After Servicing

After servicing, be sure to follow the Start Up checklist and procedure in the ProMix Operation manual.
4. Remove the plug (615) and o-ring (604) from the top of the fluid plate (606). Remove the parts of the dia­phragm assembly (613, 610, 609, 612, 617, 616). Remove and discard the dowels (623).
5. Reassemble the diaphragm assembly using the new parts from the kit. Be sure the AIR SIDE of the dia­phragm (617) faces down. Torque the nut (601) to 8-10 in-lb (0.9-1.1 N•m).
6. Install a new o-ring (602) on the pressure sensor (620) and screw the sensor into the fluid plate (606).
7. Reinstall the fluid plate on the air plate. Be careful not to pinch the pressure sensor cable. Torque the screws (605) to 30-40 in-lb (3.4-4.5 N•m).
8. Reconnect the three cables to J1, J2, and J4 on the circuit board (618). F
9. Reattach the air plate (607) to the housing (611). Torque the screws (605) to 30-40 in-lb (3.4-4.5 N•m).
10. Reattach the flow control cable and all air and fluid lines.
