Output Release Mode 2
The following applies in output release mode 2: If the actual network pressure
falls below the set switch-on pressure (p
min
) of the control, the base control
does not respond. Only when the master control issues an output release does
the base control start the compressor. A drop in network pressure to below p
min
is therefore possible. The control also switches off the compressor automati-
cally in this mode if the switch-off pressure (p
max
) is exceeded, however no
message is output. The external control is only followed once more when the
pressure drops to the switch-on pressure (p
min
).
This mode is recommended if a drop in pressure is desired or the generation
of compressed air is not required for specific periods of time (e.g. at night or at
the weekend).
Once output release mode 1 or output release mode 2 has been selected by
calling up the corresponding display (Fig. 5.6 or 5.7):
5. Press the Enter key .
 The main display reappears on the control with the symbol for the acti-
vated external output release at the bottom in the center.
 External output release is activated.
 The compressed air generation is regulated by the master control.
Performing Leakage
Measurement
(without code release)
This function is used to record the energy loss caused by leaks in the com-
pressed air network.
The control measures the duration of compressor load runs in time phases,
during which compressed air is not normally generated, for example overnight.
For an exact calculation, compressed air generation must be stopped for at
least six hours, during which time the compressor must be in the "standby /
ready" operating status. In the event of a possible drop in pressure to below
the set switch-on pressure (p
min
) – caused by leaks in the compressed air
network – the compressor automatically switches to load run to compensate
for the pressure loss. The duration of these load runs can be recorded using
the leakage measurement function and extrapolated to an annual value.
Leakages can therefore be recorded in numerical form, allowing the additional
costs incurred as a result of the energy loss to be calculated with ease. There
are two types of leakage measurement: Single measurement (LE) and
continuous measurement (Lc / LC).
During single measurement, a single measurement is taken over six hours
to calculate the number of hours spent in load run throughout the year as
a result of leaks in the compressed air network.
The start of the measurement is delayed, i.e. once the function has been
activated, the actual measurement does not start for another six hours.
The advantage of this is that the leakage measurement function can be
activated in the late afternoon, meaning that measurement will start in the
late evening and run overnight.
You can toggle between display 5.6 (mode 1) and 5.7 (mode 2) by pressing
the Info key .
