3. The display shows “SEt”, to confirm that the Auto set level has been meas-
ured and the alarm levels have been set. The display reverts to window 01.
4. If the alarm levels are too high or too low, readjust the appropriate MAR-
GINS (see table) and perform a new Auto set. Alternatively, alarm levels can
be set manually, see chapter 9.
8.7 Setting the Response Delay (windows 32
and 34)
A Response Delay allows the machine to remain in an over- or underload condi-
tion for a specific time before the alarm relays are activated. Set the response
delay for the overload condition in window 32 (max.), and set the response
delay for the underload condition in window 34 (min.). The default value for
both windows are 0.5 s. The valves may be adjusted upwards to avoid triggering
a “false alarm”.
Programming
1. Determine in seconds the response delay required for both overload and
underload conditions. This is normally determined by the unique properties
and behaviour of each application.
2. Go to window 32 (overload, default = 0.5 s).
3. Press or to set the determined Response Delay time in seconds.
4. Press to confirm the change.
The response delay for the underload condition (min.) is set in window 34 in a
similar way.
