NOTICE
If the U input is not supplied on start-up, the state
AUX
machine only transitions to state U
the Enable U control bit is set to 0 (active). If, at a later
AUX
stage, the U input is provided, then the state machine
AUX
advances to state Standby.
3.2.1 Relay Outputs
The SAB has 2 relays:
•
Relay 1: 0x200D (see chapter 8.8 Object 0x200D:
Relay 1 Control).
•
Relay 2: 0x200E (see chapter 8.9 Object 0x200E:
Relay 2 Control).
Select the functionality of the relay via the corresponding
parameter (see Table 3.2). There is 1 parameter for each
relay for setting the On delay time and 1 for the Off delay
time. Both delay times are independently adjustable from
0 s (default) to 10 minutes and the adjustment is possible
in 1-second steps. The default setting for the relays is No
operation. The function of the on and off delay time is
described in Illustration 3.3.
