The factory defaults are as follows (see the illustration on the left):
– Operation as a current interface
– Range of current intensity: 4 to 20 mA
– Voltage supply: internal

Operation as a Current Interface in the 4 to 20 mA Range (Factory Setting):
§ Solder bridges 1 and 2 must be configured as shown in the illustration on the left.
2
Operation as a Current Interface in the 0 to 20 mA Range:
§ Re-solder bridge 1 as shown in the illustration on the left.
2
§ Solder bridge 2 must be configured as shown in the illustration on the left. This
corresponds to the factory default configuration.
Operation as a Voltage Interface (0 to 5 V):
§ Open solder bridge 1 so that the setting corresponds to that shown here on the left.
2
§ Re-solder bridge 2 as shown in the illustration.
Operation with Internal Voltage Supply (Factory Setting):
§ Solder bridges 3 and 4 must be configured as shown in the illustration on the left.
Operation with External Voltage Supply:
§ Open solder bridge 3.
§ Re-solder bridge 4 as shown in the illustration.
Operation as an Electrically Isolated Interface:
§ Configure solder bridges 3 and 4 for "external supply." To do this, open solder bridge
3 and re-solder bridge 4 as shown in the illustration.
§ If the interface is powered by an external AC adapter, it must be electrically isolated.
Be sure to comply with the requirements of CE conformity.
Notes
– The shielding in the current interface connecting cable is connected at one end to the
housing of the indicator.
– The indicator is connected to the protective grounding conductor.
– The current interface cannot be operated when the indicator is powered by the external
rechargeable battery pack.
§ The YDA01C-20MA interface module (Option A4) is installed directly on the digital PCB
in the Combics indicator (models CISL., CIS., CW.P, CW.S). For details, please see
"Installation in the Indicator."
