NAMUR-signal:
The F116-P is suitable for flowmeters with an NAMUR signal. The standard F116-P is not able to
power the NAMUR sensor, as an external power supply for the sensor is required. However, a 8.2V
sensor supply voltage (terminal 11) can be provided with type PD, PF, PM.

Terminal 26-31: type CB / CH / CI / CT - communication RS232 / RS485 / TTL (option)
For connections, refer to figure: Overview of terminal connectors - Standard configuration and options
Full serial communications and computer control in accordance with RS232 (length of cable max. 15
meters) or RS485 (length of cable max. 1200 meters) is possible.
When using the RS232 communication option, terminal 27 is used for supplying the interface.
Please connect the DTR (or the RTS) signal of the interface to this terminal and set it active (+12V).
If no active signal is available it is possible to connect a separate supply between terminals
26 and 27 with a voltage between 8V and 24V.
Terminal 00 - 01: type ZB backlight (option):
If the unit is supplied with a power supply:
type PD, PF or PM, the backlight supply is integrated.
type PX, use the terminals 00 and 01 to supply the backlight.
The backlight intensity is set in the setup menu: Display.
