35
the previous activation
It establishes the time that disables the compressor activation from the
moment of the previous compressor activation.
For further informations about the parameter C 1 meaning see the
paragraph Compressors protection on the page 10.
C 2
disabling time to the compressor activation from
the previous deactivation
It establishes the time that disables the compressor activation from the
moment of the previous compressor deactivation.
For further informations about the parameter C 2 meaning see the
paragraph Compressors protection on the page 10.
C 6
number of power steps loaded during a suction
probe failure alarm
It establishes the number of power steps loaded during a suction probe
failure alarm, except what established with the parameters r 8 and r 9
and except what established with the disabling times to the compres-
sors activation (see the paragraph Alarms on the page 46).
C 7
number of running working hours of the power
step enough to request the unloading
It establishes the number of running working hours of a power step
enough to request the power step unloading (for instance, when the
conditions will permit it, the instrument will unload at first the power
step who will have the number of running working hours established
with the parameter C 7).
C H
number of total working hours of the power step
enough to signal the request of service
It establishes the number of total working hours of a power step enough
to signal the request of service (see the paragraph Alarms on the page
46).

Notes
• the symbol (1) indicates that the parameter is available both to
the first and to the second level
• the symbol (4) indicates that the unit of measure depends from
the parameter /bE (the parameter /bE belongs to the User
Menu; see the chapter User Menu on the page 32): if the
condensing probe is a 2 wires 4-20 mA pressure transducer

For further informations about the parameter r A meaning see the
paragraph Suction pressure regulation on the page 9.
r C
kind of choking valve
It establishes the kind of choking valve that the instrument must man-
age, as indicated:
0
= NC choking valve
1 = NO choking valve.
For further informations about the parameter r C meaning see the
paragraph Suction pressure regulation on the page 9.
r E
increase (percentage) of the “neutral zone”
(parameter r 0) given by the activation of the
input by-pass regulation
It sets the increase (percentage) of the “neutral zone” (parameter r 0)
when one activates the input for by-pass regulation (the instrument will
automatically increase the “neutral zone” applied over the working
setpoint; for example, set 100 % to double the value).
r F
maximum time the activation of the input by-pass
regulation has effect
It sets the maximum time the activation of the input by-pass regulation
has effect; as soon as this time passes, the instrument will automatically
recover the normal operation, even is the input is activated; if the
parameter has value 0, the instrument will consider 99 min).
