See Secon ‘6.1 Status messages’ for more informaon about each mode.
How the unit moves from one operaon mode to another is explained below. See also
Figure 18 for a ow chart showing how the unit goes through its four dierent operaon
modes.
As discussed in Secon ‘5.3 Start the unit’, when the unit is in O mode, the unit can be put
into Standby mode with its motor o and the Filter Cleaning Valve (FCV) closed by pressing
the Standby/Running buon. While the unit is in Standby mode, the unit can be put back
into O mode again by pressing the Standby/Running buon.
The unit goes from Standby mode into Running mode when it receives a pilot signal by a
valve being opened at one or more work staons (in other words, someone starts to work).
The unit’s motor is now on and the FCV is closed. The DIR_Time and SSR_Time mers are
not started, see Secons ‘7.2.2 DIR_Time’ and ‘7.2.1 SSR_Time’.
The unit stays in Running mode as long as there is an acve pilot signal. However, the unit
can sll be put into O mode by pressing the Standby/Running buon.
Note that if only one workstaon is connected to the unit, or if only one work staon is
in use and work stops at that one staon, the pilot signal stops. If there is more than one
work staon connected to the unit, and more than one work staon is in use, the pilot
signal only stops if work stops at all workstaons (in other words, all valves close).
When the pilot signal stops, the DIR and SSR mers start. If work resumes at one or more
work staons within 10 seconds, the unit stays in Running mode. The DIR and SSR mers
are reset back to zero and are stopped.
If DIR_Time is set for 10 seconds (default), and the pause in work is longer than 10 seconds,
DIR_Time elapses. The unit then goes into Idling mode with its motor on and the FCV open.
If a new pilot signal is sent within 12 minutes, the unit goes back into Running mode. The
DIR and SSR mers are again reset to zero and are stopped. However, if SSR_Time is set for
12 minutes, which is the default seng, and there is no new pilot signal within 12 minutes,
SSR_Time also elapses.
The unit then goes into Standby mode unl it either receives a new pilot signal that puts
the unit back into Running mode, or the unit is turned o (in other words, put into O
mode) by the weekly mer, see ‘7.2.3 Weekly mer’, or by pressing the Standby/Running
buon.
