OM4207 04/10 Automatic Lubrication System - Section 42 42-11 SYSTEM CHECK To check system operation (not including timer), pro- ceed as follows: The fourth dip switch is used to select “memory off” or “memory on”. When the switch is set to “memory off”, a lube cycle will occur each time power is turned on. The lube cycle will start at the beginning of the on time set- ting. 1. Start the engine. 2. Actuate the lube system test switch at the reser- voir/pump assembly. 3. The motor and pump should operate until the sys- tem attains 17 237 kPa (2500 psi). When the switch is set to “memory on”, the controller will function as follows:
When power is turned off between lube cycles, the lube cycle will resume at the point of inter- ruption after power is restored. In other words, the controller will remember its position in the cycle. When power is turned off during a cycle, the controller will reset to the beginning of the lube cycle after power is restored. 4. Once the required pressure is achieved, turn the pump motor off. The system should vent. 5. Check for pump, hose or injector damage. Check for leakage with the system pressurized. 6. After checking the system, shut the engine off. Lubrication Controller Check Pressing the manual lube button on the enclosure cover will initiate a lube event. (See Figure 42-9).
Off time switch (1) is used to select units of time. Possi- ble time intervals are: 0.5, 1, 2, 4, 8, 15, 24 or 30. The mode switch determines whether the off time units will be minutes or hours. The time between lube events is determined by the set- ting of the rotary switch and the dip switch. The rotary switch selects the numeral setting, and the dip switch selects the units in either minutes or hours. Lubrication Controller Operation Cover (3) contains three Light Emitting Diode (LED) windows and a manual lube switch. The LED’s indicate system operation and status. When power is on, a green LED will illuminate. When the pump is on, another green LED will illuminate.
A red LED will illumi- nate when an alarm condition occurs. Lubrication Controller Components The manual lube switch, when depressed, will initiate a lube cycle. Mode switch (2, Figure 42-9) consists of four dip switches. The first dip switch controls the maximum amount of “on time”, either 30 seconds or 120 seconds. The second dip switch controls the mode, either timer mode or controller mode. When the switch is set to the timer mode, the amount of time that the pump is on will be determined by the setting of the dip switch - 30 sec- onds or 120 seconds. When the switch is set to the controller mode, a pressure switch must be installed in the lube supply line.
The pressure switch will detect supply line pressure, and will reset the timer at a set pressure. If the pump fails to reach the set pressure within the dip switch set time, the controller will initiate an alarm.
