2.6 Configuration Jumpers
For setting some pre-defined basic features, configuration jumpers are used. There are two
jumpers available on the main board (see Fig. 5 for jumper location).
Jumper CV18 - for configuration of DC power mode (internal or external).
Jumper CV22 - for CAUTION output configuration if relays are used
For jumper identification on the main board refer to Fig. 5.
2.7 Output Signals
Relay Outputs
The control units are equipped with four SPDT relays 8A/250 VAC:
• 2 relays related to WARNING, and ALARM status,
• 1 relay related to FAILURE status
• 1 relay that can operate the external HORN.
For more information about backplane terminal board connection see chapter 3.2.
Voltage-free contacts must be used according to electrical characteristics are listed in chapter 9.
The control unit with relay outputs can be configured using Access Code 52: For more information
see chapter 5.7.
If the opto-isolated CAUTION output is used and 24 VDC external power supply is not available
then set CV22 in position 2-3 and CV18 in position 1-2.
Analog Outputs
The control unit provides independent analog outputs for each channel. The output signal can be
configured using Access Code 2 and Access Code 4.
0-20 mA, 4-20 mA, 20-0 mA or 20-4 mA output signal can be set. For more information see
chapter 5.2.
Jumper No. Position Function
CV18 1-2
Internal 24 VDC power supply is used to supply the external auxiliary
circuits (e.g. relays, interfaces, transmitters, etc.)
CV18 2-3
External 24 VDC power supply is used (e.g.: battery backup, power
supply modules, etc.)
Jumper No. Position Function
CV22 1-2
Opto-isolated CAUTION output needs the external negative on
terminal 7
CV22 2-3
Opto-isolated CAUTION output uses the negative as common to the
default board
CAUTION alarm is designed as an opto-isolated output only.
Common relay outputs are used for both channels related to Control Unit 9020 SIL.
