Connecting to the AX1 module
Analogue Extension Module AX1
Terminal
no.

Remark
1
AGND
Analogue common connection (or ground)
2
DIM/HV3+ Dimmer input configurable in the range, max. 30 V DC, port 3
It can be configured as an extra high voltage indicator input (max. +/-30 V DC), if it is
not used for dimmer.
3
REF
REF out typ. 7.3 V DC (min. 7
V…max 7.5
V) and max. 10 mA.
This port can also be used as reference potentiometer input, if the external voltage
applied is between 7.5 V and 30 V DC.
4
HI2-
Negative input for: High current input (max. +/- 20 mA DC), port 2
5
HI2+/LIV2+ Positive input for: Low voltage, low current or high current, port 2
6
LIV2-/HV2- Negative input for: Low voltage (max. +/-2 V DC) or Low current (+/- 2 mA DC), port 2
7
HV2+
Positive input for: High voltage (+/-30 V DC), port 1
8
HI1-
Negative input for: High current input (max. +/- 20 mA DC), port 1
9
HI1+/LIV1+ Positive input for: Low voltage, low current or high current, port 1
10
LIV1-/HV1- Negative input for: Low voltage (max. +/-2 V DC) or Low current (+/- 2 mA DC), port 1
11
HV1+
Positive input for: High voltage (+/-30 V DC), port 1
The input wiring to the AX1 module must be in accordance with this table:

REF out voltage
Terminal 1, analogue common (AGND), is used as the common connection for input REF,
HV1+, HV2+ and DIM/HV3+ .
IMPORTANT: Only one input signal (voltage or current) must be connected to an input port,
so be careful not to connect 2 different sets of input wires to the same input port!
