Digital inputs and outputs
Digital inputs and outputs are gathered in
X16.
All of them are isolated and configurable.
Specifically, there are 5 digital inputs which operate at 24 V and 3 relay digital outputs.
The list of each digital functionality is the following (Note that those are
default
functionalities). (The maximum admitted input voltage is 10V and 12 output voltage)
-
DIG_IN_1:
Enable console mode
-
DIG_IN_2:
Run equipment
-
DIG_IN_3:
Not used
-
DIG_IN_4:
Rearme (used in combination: DI DIG_IN_5 = Reset / DI
DIG_IN_2 = Enable)
-
DIG_IN_5:
Single push: Ready. Long push (2 seconds): disable
Please note that
DIG_IN_1
must be ON during console mode, and while it is ON, remote
control is not possible.
Relay normally open output contact (3A, 250VAC / 3A, 30VDC)
-
DIG_OUT_1_NO:
Run (signal in run, ready and initialization)
-
DIG_OUT_2_NO:
Alarm (signal in alarm and initialization)
-
DIG_OUT_3_NO:
Ready (signal in ready, initialization and blinking during precharge)
In standby, none of the digital output is activated.
In initialization, all digital outputs are activated.

Analog inputs and outputs
Analog inputs and outputs are gathered in
X17
.
The analog input of GE is isolated and accept a voltage range from 0 to 10Vdc. There is only one
analog input (
ANALOG_IN_1
) and it corresponds to the voltage setpoint for all three phases in
case of AC mode. If the analog input is set to zero volts, that corresponds to 0V. In this way, by
setting 10V, the GE will supply the rated voltage specified in the datasheet.
In case of DC mode, the analog input (
ANALOG_IN_1
) controls voltage, current or power
depending on the control mode selected through the LCD touchscreen. The analogue input
controls all three phases in the three different control mode. In case of power or current, the
analog input controls both positive and negative parts and has the following relation:
