46 Condair CRC and CRC-NA
3.8.4 Connecting the CRC or CRC-NA to the Condair EL/EL OC
1. Connect the CRC to the corresponding terminals on the driver board of the Condair EL/EL OC (ROW)
according to the following diagram.
Note: The voltage supply of the CRC is established via the terminals "V+" and "GND" of terminal
block "X8" or via an external 24 V AC/DC voltage supply.

Connect the CRC-NA to the appropriate terminals of the terminal block "XE2" of the Condair EL/EL
OC (NA) according to the following diagram.
Note: The voltage supply of the CRC-NA is established via the terminals "24VDC/10VDC" and "GND"
of terminal block "XE2" or via an external 24 V AC/DC voltage supply.

2. Set a jumper on JP1-24V on the driver board of the Condair EL/EL OC.
3. Only for CRC: Set the output signal of the CRC to "0-10V" using the Jumpers JP1 and JP3 on the
control board of the CRC.
Note: other output signal settings (e.g. 4-20mA) are also possible, see CRC jumper settings in Sec-
tion 3.7.
