16. CENTRALIZED TECHNICAL CONTROL (GTC) CONNECTION

The controller in its standard version has an integrated RS485
communication port (to be used with an STP cable).
The standard controller can communicate in Modbus RTU via its
RS485 port by simply activating an internal parameter.
If you need to integrate the CADB-N PRO-REG unit on a Modbus
RTU system, ask for our communication manual where the Mod-
bus technical specifi cations and list of available registers appear.
To enable Modbus communication acces as administrator is re-
quired(see point 18).

17. REPLACEMENT OF THE BATTERY FROM THE CORRIGO PROGRAMMABLE LOGIC CONTROLLER

When the "battery low" alarm appears and the red indicator light is lit, it means that the backup battery
to save the memory and the real time clock is too low.
The procedure to change the battery is described below.
A capacitor allows backing up the memory and running the clock for approximately 10 minutes after
the power is switched off.
If the battery can be changed in less than 10 minutes, the program does not have to be reloaded and
the clock will continue to run normally.
The spare battery is type CR2032.
• Using a small screwdriver, pry up
the clips on each side of the case
to release the cover from the base.
• Hold the base and remove the cover.
• Grasp the battery and pull up gen-
tly until the battery exits from its
holder.
• Replace the battery with a new.
Warning: be sure to respect the
polarity when inserting the battery.
