T6 Maintenance and attendance
Lauer EPC X appliances only need minimal maintenance and attendance.
Nevertheless, please observe the following information:
Changing the batteries The appliance is equipped with an integrated lithium battery to buffer the
data of both the real-time clock, and the integrated SRAM storage.
Type of battery: CR2032, 3V/230mAh
Manufacturer: Varta, type 6032
Buffer current: 2µA typ / 15 µA max
Control of battery voltage: yes (functionality depends on the software)
Lasting of battery (typ.): 5 years
The lasting of the battery always depends on the ambiance conditions
(working temperature, connecting/disconnecting time, air moisture). The
indicated lasting is based on the fact that the appliance is switched on
regularly (several days per week, resp. at least 1 500 hours per year.
The battery may only be changed by trained experts. Please observe the
ESD protection measures. We recommend to always have the battery
changed by „Elektronik-Systeme LAUER GmbH & Co. KG.“
Please switch off the appliance’s tension before changing the battery.
Before changing the batteries, the EPCX 550-appliances have to be
removed from the switch cupboard’s casket. Afterwards, you must loosen
the four flange-head screws (hexagon socket screw, 2.0 mm).
The appliances EPCX 640 to EPCX 1000 need not necessarily be
removed from the switch cupboard. In their case, it suffices to loosen the
screws at the rear sheet metal (hexagon socket screw, size 2.0), and to
tilt the rear sheet metal downwards. Please hold the rear sheet metal
approximately horizontally with one hand.
Please use a plastic part (e.g. Touch pen) to press the battery’s contact
spring backwards until the battery springs out of the holding device.
Remove the battery. Insert the new battery into the battery tray, and lock
it. While doing so, the battery’s positive pole must show upwards,
respectively be visible!!
Caution!
When the battery is changed, the data in the SRAM-dump and in the
real-time clock get lost.
NO manipulations at the appliance are permitted during the period of
liability for defects!
