Terminal 09-11: Type A – Flowmeter input (general)
The F110-A requires a (0)4-20mA flowmeter signal which will be processed 4 times a second with a
14 bits accuracy. The input is not isolated.
For Intrinsically safe applications (without input loop power): please read chapter 5.
Terminal 09-10: Type A-PL – Flowmeter input / power supply
:
The F110-A-PL requires a 4-20mA flowmeter signal which has a double function:
The signal will be processed 4 times a second with a 14 bits accuracy and the unit will be powered
from the sensor signal (input loop powered). The input is not isolated and not intrinsically safe.
Terminal 12-13: Type IB – external reset (option):
With this function the total can be reset to zero with an external switch. The Total resets only when
the switch
opens
. When closed Total still counts but the ”Clear Total” function is disabled (see
chapter 2).
The input must be switched with a potential free contact to the GND-terminal number 12.
