When the end-of-charging voltage set at the factory is reached for the connected
battery, the energy cell starts to idle. The energy cell is switched off manually by turning
the keylock switch to the - O - position as described under „Manual mode: switching off
the energy cell“.
1. In Standby mode, briefly turn the keylock switch to the - Start - position and release
The keylock switch returns to the - I - position
The energy cell runs through a test phase. The display reads „Starting“, together
with the current status of the system test or the subsequent startup phase.
When the test phase is completed successfully, the display reads „Startup Complete“.
To switch off the energy cell manually
1. Turn the keylock switch to the - O - position
The energy cell is completely switched off when the keylock switch has been turned to
the - O - position.
Once the energy cell has been completely switched off, it is in the „safe state“. In this
state, there is no power to any of the valves controlled by the energy cell.
The electrical connection to the connected battery is also disconnected.

When the connected battery reaches a critical charge level, a higher-level control unit
sends a start signal to the energy cell as described in the „Starting the energy cell -
automatic mode“ section. The energy cell then starts automatically. Once the final
charging voltage set at the factory for the connected battery has been reached, the
higher-level control unit cancels the start signal (X2), causing the device to start to run
down.

For the energy cell to remain swit-
ched on there must be a voltage of 10
- 30 V applied at pins 1 and 2 of the
safety-related input X2 - External
standby.
Maximum cross-section of voltage
signal cable: 2.5 mm² (0.00388 in.²)
IMPORTANT!
The recommended tighte-
ning torque for the locking screws in the
plug is 0.6 Nm.
IMPORTANT!
The energy cell can be started with a voltage signal of 10 - 30 V on pins
4 and 5 of input X4. The required voltage signal must be preset by a higher-level control
unit. The keylock switch no longer works in this automatic mode. The energy cell must
also not already be on Standby for the start process, which means that it can also be
operated out of the safe state.
