7. Operation
To switch on the DPSI RV, the 2 mm (0.08”) pin plug is pulled from the
disconnect socket (black) and plugged into the turn-on socket (red).
The red, ultra light LED in the switch and on the circuit board of the
DPSI RV (not DPSI 2001 RV) light up. This signals operation.
Immediately after switching on, the signal transmitter (buzzer) plays
back the programmed battery type (one, two, three, four or five beeps).
Following this, the algorithm for error detection (or voltage monitoring)
is started.
If one of the batteries is not connected, the DPSI RV starts in
programming mode. This program mode is automatically abandoned
after approximately 30 seconds. During this approximately 30-second
interval, the missing battery must not be connected unless new
programming of the battery type is desired.
Hint:
If the DPSI buzzer sounds for 3 seconds right after turning on, only one battery is
connected to the DPSI and the device starts working in the programming mode. If
no reprogramming is desired, one can either turn the DPSI off or wait for
approximately 30 seconds and connect the second battery.
Hint:
A wrong battery type is probably programmed should the DPSI sound error
codes shortly after turning on the device even with fully charged batteries.
Possibly a battery is used, with a too high internal resistance and breaking down
under heavy load (e.g. NiMH batteries in “AA” -Mignon size). Therefore, only
batteries with high current load capability are to be used!
In the case of a lost pin, you can help yourself by using a 2 mm (0.08”)
wire or screw, which is simply put into the corresponding socket in
order to the DPSI on or off.
