Fig. 6 - Printed circuit board 236-13870-1
• The printed circuit board automatically controls the

sequence of the pause and operating times of the 203

central lubrication pump as a function of the vehicle or

machine working hours tB (Fig. 7).

• The sequence of the pause and operating times is

activated when the machine contact or ignition switch is

switched on.

• A lubrication cycle consists of one pause time and one

operating time. Once the pause time has elapsed, the

operating time starts to run. This lubrication cycle is

repeated permanently after the machine or vehicle has

been put into operation. Refer to Fig. 7.

• During the operating time the pump element dispenses

the lubricant to the lubrication points via progressive me-

tering devices.

Pause time

• The pause time

- determines the frequency of the lubrication cycles within a

working cycle;

- is started and stopped via the machine contact or

ignition switch;

- is adjustable.

• When the machine contact or the ignition switch is

switched off, the pause times which have already

elapsed as well as the momentary operating conditions

(faults) are stored and added up by an electronic memory

(EEPROM) until the time which has been set on the blue

rotary switch is reached.

• After the machine contact or ignition switch is switched

on again, the printed circuit board operates from the

point where it had been interrupted.

• If the setting is modified within the pause time, the printed

circuit board takes over the new value only at the end of the

operating time.

• The pause time setting may be different for each applica-

tion. It must be adjusted in accordance with the respective

lubrication cycles. Also refer to ”To set the pause time”.

Fig. 8 - Proximity Switch

Operating time

• A 

proximity switch

 (initiator) which has been installed on

a metering device instead of a piston closure plug moni-

tors and brings the pump operating time to a close after

all the pistons of this metering device have dispensed

their

lubricant quantity.

• The operating time depends on the system’s lubricant

requirement and on the location of the proximity switch

(either on the main metering device or on the secondary

metering device).

• During the operating time, the 

signal lamp is

permanently 

lit.

Monitoring time

• A fixed 

monitoring time

 of maximum 30 minutes.

Note: Normally, the monitoring time ends at the same time

as the operating time.

• If there is 

no switching off signal

 from the proximity switch

to the printed circuit board within 30 minutes, a

 fault

signal 

will occur.

The signal lamp flashes with the corresponding flashing

frequency. See ”Fault indication”.
