Operating instructions

NOTE
The maximum current for the analog outputs 0-10V is
1mA.
NOTE
Where Live Zero Monitoring is used, it is important that
any analog inputs not being used for the frequency
controller, i.e. being used as part of the Building
Management System decentral I/O, should have their
Live Zero function disabled.

Table 3.3: Relevant parameters
It is also possible to read the analog inputs, write to the analog
outputs and control the relays, using communication via the
serial bus. In this instance, these are the relevant parameters.

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.
