Maintenance - Section 4 OM4006.2 10/98 Page 4-20 Automatic Lube System Pump Cycle Timer (Flasher Timer): Pump Cycle Timer (Flasher Timer) Adjustment: The Pump Cycle Timer mounts on SV2 solenoid and generates a timed pulse signal to control the recipro- cating cycle rate of the grease pump. The Pump Cycle timer is factory set at 1 second ‘‘On’’ and 1 second ‘‘Off’’ for 30 cycles/minute. If adjustment is necessary, refer to Figure 4-9 and the following procedure. Pump Cycle Timer (Flasher Timer) Installation The one adjustment screw adjusts both the ‘‘On’’ time and ‘‘Off’’ time equally. The adjustment range is from 0.5 seconds (60 cycles/minute) to 5.0 seconds (6 cy- cles/minute).
The adjustment screw allows 15 turns of adjustment over the timing range. 1. Connect cycle timer to SV2. Be sure to install gasket. 2. Connect the ‘‘Sol’’ from the Solid State Timer to the Brown wire from the Cycle Timer and one of the wires coming from SV1. 1. The adjustment screw should be turned 20 turns counter-clockwise to insure a minimum start point. 3. Connect the White wire from the Cycle Timer and the other (gnd) wire coming from SV1. NOTE: The timer cannot be adjusted below minimum - additional turns counter-clockwise have no effect . 2. Each clockwise turn of the adjustment screw will equal approximately 0.3 seconds. 3.
Add the number of turns clockwise to reach the approximate desired timing. Some additional adjustment may be necessary depending on the accuracy needed. FIGURE 4-9.
