When next electrify starts, the control unit will continue carrying out operation from last point of power-off.

The control unit stores operating status and values in EEPROM. The data can reliable be stored for 10 years.

6. Faults

When the control unit detects system faults, LED "FAULT" on the panel will be flashing quickly. If an external Signal Light has been installed, light "SL" will be also flashing to remind user the lubrication system is in fault. Meanwhile, the control unit stops normal operation and wait for user to handle the faults. User may check the detailed cause of the fault through LCD.

6.1 Display faults

Briefly press or to start the display of fault messages.

The meaning of the display are as followings:

PRESSURE SWITCH: No signal is received from pressure switch during pump running time.

CYCLE SWITCH:

LOW LEVEL:

SYSTEM ERROR:

No signal is received from cycle switch during pump running time.

The filling level in lubricant tank has dropped below the minimum level.

6.2 Clear fault messages

Press

DK to acknowledge and clear fault messages, and to start a normal lubrication cycle.

Please note:

DK must been used after determining and correcting the faults. The user himself is liable for any damages caused by operating the equipment without lubrication.

6.3 Block operation

If CS (Cycle Switch) is programmed, a block operation will be automatically activated when no signal from the cycle switch is received during the pump running time. To test Cycle Switch:



1. When no signal from CS is received during the pump running period, the normal

1. lubrication operation will be aborted, then a 15 min interval block operation begins.

2. When the 1st 15 min block interval ends, it drives the pump. If signal from CS is received,

1. the block operation will be aborted. System goes back to normal lubrication cycle.

1. If there is still no signal from CS, then another block operation begins.

3.If signal from CS is received during the 2nd 15 min interval, the block operation is aborted

1. and the system will go back to normal operation. If there is no signal from CS, then the

1. 3rd block operation begins.

4.If the system receives signals from CS during the 3rd 15 min interval, then it will go back

1. to normal lubrication cycle. If there is still no signal received, then the block operation is

1. aborted and a fault message is displayed.

If the preset PAUSE time is shorter than 15 min, the block pause will correspond to the preset value. During block operation, relevant LED on the control panel will be flashing to indicate that the control unit is now performing block operation. LED "CS" flashes alternative with LED "PAUSE" means the control unit is now in the Pause phase of the block operation.

LED "CS" flashes alternative with LED "CONTACT" indicates the control unit is now in Drive phase of the block operation.

6.4 No signal from pressure switch

If PS (Pressure Switch) monitoring is programmed, normal operation will automatically stop when no signal from the pressure switch is received during the pump running. And a fault message is displayed.

6.5 Storage of fault messages

The time that has elapsed since the occurrence of the fault message up to its acknowledgement will be added up and saved automatically. And the saved fault time is not erasable.

The maximum savable fault time is 999 999 hrs and 59 min. And the minimum savable fault interval is 1 minute.
