Data Sheet 09.02
Electronic timer as a stand-alone unit, particularly suitable for use with Lumiglas luminaires and other electrical equipment operated in potentially explosive environments.
• This data sheet also serves as installation and operating
instructions
• Applications:
The timer enables consumer loads, such as e. g. the illumination
system for process sequences, to be operated in a time-
dependent manner. The timer is wired into the power line to
the consumer load, consequently allowing the power to be
switched according to the time setting.
Pressing the button of the combined push-button/selector
switch activates the consumer load for the preset time which
has previously been programmed to meet the customer’s
specific needs. Continuous ON mode can also be selected via the combined push-button/selector switch.
Alternatively, the device can be programmed to function as a flashing relay.
• General operating conditions:
- Approved for use in potentially explosive environments,
Zones 1 and 2 as well as Zones 21 and 22
- Approved for use in ambient temperatures of between
-20°C and +40°C
• Function:
1. As a timer
The combined push-button/selector switch on the front of the
timer housing has a zero setting (marked ‘off’), a momentary-
contact switch (marked ‘time’) and a latched position for
continuous operation (marked ‘on’).
Turning the switch anti-clockwise starts the timer and turns on
the power to the consumer load.
Once the preset time has elapsed, the consumer is automatically
switched off. By actuating the push-button again before the
programmed time has elapsed, the timer will start a full
cycle again.
By turning the selector switch clockwise to the latched position,
the consumer load will run in continuous mode. This is deacti-
vated by turning the switch back to the off/0 position.
2. As a flashing relay
If the device is intended as a flashing light relay – the relevant
programming and predefinition is carried out by the manu-
facturer – the flashing function is switched on once the supply
voltage is applied. The combined push-button/selector switch
is not in operation in this mode and is set to ‘0’. The flashing
sequence stops once the power supply is interrupted.
• Setting the time or flashing sequence:
The time sequence is variable between 10 sec. and 60 min.
In flashing mode, the ‘on’ and ‘off’ phases can be indepen-
dently set at between 1 sec. and 20 sec.
Example: ‘on’ for 5 sec. – ‘off’ for 10 sec., etc.
The data is factory-set by the manufacturer acc. to the customer’s specifications and indicated on a label affixed to the device. Apart from the designated function of the unit as a ‘Timer’ or as a ‘Flasher’, the time interval in the case of the timer and the flashing sequence for the flasher function are also shown.

• Please note:
Any intended reprogramming or modification to the
function or the time cycles must be carried out outside the potentially explosive area and only by appropriately trained personnel of the manufacturer (F.H. Papenmeier GmbH & Co. KG) who shall use tools and equipment specially
designed for this purpose.
