4a. Master Divider Valve Equipped With Performance

Indicator

With manual pump connected to the master divider valve as outlined in Locating Blockages, Step 3, raise pressure to 2000 psi. The indicators in the indicator ports will signal the location of the block- age. An indicator in the up position indicates pres- sure is in that outgoing line and signals the blockage is in the area being served from this outlet (FIG. 11).

If no indicator pins are protruding, the blockage is in the master divider valve.

Indicator

1)With manual pump connected to the master divider valve as outlined in Locating Blockages, Step 3, raise pressure to 2000 psi.

2)Remove, one at a time, each indicator port plug and attempt to operate manual pump after each plug is removed. Do not exceed 2000 psi.

3)If pressure drops and the master cycles freely after an indicator port plug is removed, then blockage is downstream in the area that is being served from that outlet. See Locating Block- ages, Step 3.

NOTE:

If all indicator port plugs are removed, the master will not cycle. Blockage is in this divider valve.

When indicator port plug of a blocked area is removed, a small shot of trapped lubricant will usu- ally surge out of this outlet as the inlet pressure on the divider valve drops.

If testing (Step 4) indicates a blockage in the master divider valve, this divider valve must be disassem- bled and cleaned. See Clean Divider Valve, Step 7, page 15.

5.If in Step 4, a blockage has been indicated downstream of the master divider valve, install a manual pump in the indicator port of the master divider valve that is common to the blocked area. (See FIG. 12).

a.Proceed to downstream secondary divider valve and remove all indicator port plugs.

b.Slowly operate manual pump. If lubricant can be discharged freely through each of the indicator ports of this divider valve, the blockage is not in the supply line or the divider valve. Go to step 6.

If lubricant is not freely discharged through open indicator ports of the second divider valve, the blockage is in this divider valve or its supply line. Disconnect supply line at secondary inlet
