3.4 Power up
The control console is designed to operate from a power source that will not apply more than
13-30 Volts DC
between the supply terminals
V+
and
V-
(Negative ground only).
A protective ground connection by way of the grounding terminal is essential for safe operation as well as a good
clean power supply.
Note!
A load of 85 - 1000 Ohms between terminals 1-4 is required for the controller to power up, e.g. the load cell
must be connected for the controller to operate correctly.
The controller memory has a lithium back-up battery (CR2450) which
must be engaged after power-up to
ensure correct memorisation
. As soon as power has been applied to the controller, the battery may be engaged
by pulling the plastic tab on the rear side of the controller.
If the tab has accidentally been pulled before power-up, just connect the controller to 24vdc for power-up and then
disconnect again. This will allow the internal CPU to perform a controlled shutdown, minimizing battery drain.
Note that if the controller will be stored for a long period of time before taken into operation, it will be better not to
engage the battery. Parameter settings can be permanently stored to a flash memory anyway from inside the
menusystem, for future restore without the need for battery to be activated.
The battery will keep the memory with time and date activated for approx. 1 year without power supply.
Regarding battery exchange - contact your local S-E-G representative for information.
