Table 3.4: Relevant parameters
Setting of on-board Real Time Clock.
The Analog I/O option incorporates a real time clock with battery back-up. This can be used as back up of the clock function included in the frequency
converter as standard. See section Clock Settings, parameter group 0-7*.
The Analog I/O option can be used for the control of devices such as actuators or valves, using the Extended Closed loop facility, thus removing control
from the Building Management System. See section Parameters: Ext. Closed Loop – FC 100 parameter group 21-**. There are three independent closed
loop PID controllers.
3.24.2 26-0* Analog I/O Mode
Parameter group for setting up the analog I/O configuration. The option is equipped with 3 analog inputs. These analog inputs can be freely allocated
to either voltage (0V - +10V), Pt 1000 or Ni 1000 temperature sensor input.
26-00 Terminal X42/1 Mode
Option: Function:
Terminal X42/1 can be programmed as an analog input accepting a voltage or input from either
Pt1000 (1000 Ω at 0°C) or Ni 1000 (1000 Ω at 0°C) temperature sensors. Select the desired mode.

Ni 1000
[4] if operating in Celsius - Pt 1000 [3] and Ni 1000 [5] if operating in
Fahrenheit.
Notice: If the input is not in use, it must be set for Voltage!
If set for temperature and used as feed back, the unit must be set for either Celsius or Fahrenheit
