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, par 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 existing control system. See
section Parameters: Ext. Closed Loop – FC 200 par 21-**. There are three independent closed
loop PID controllers.

[5] Ni 1000 (°F) Terminal X42/1 can be programmed as an analog input accept-
ing 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.

[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 (par. 20-12, 21-10, 21-30 or
21-50)
