DIMENSIONS AND INSTALLATION
Control module dimensions and installation
The dimensions are expressed in mm (in); installation is envisioned on a flat surface, with shims.
Notes:
(1)
the unit of measurement depends on P2
(2)
Properly set the parameters corresponding to the
regulators after modifying parameter P2
(3)
the value depends on parameter P2 (0.1 °C or 1
°F)
(4)
the parameter has effect even after an interrup-
tion in the power supply that occurs while the
device is switched on
(5)
the time established with the parameter is counted
even when the device is switched off
(6)
if parameter C1 is set at 0, the delay after the end
of the cell probe error will be 2 min
(7)
if parameter C2 is set at 0, the device will function
as if parameter C18 were set at 0
(8)
The parameter differential is 2.0 °/4 °F
(9)
if when the device is switched on, the condenser
temperature is already above that established in
parameter C7, then parameter C8 will not have
effect
(10)
compressor 2 is switched off when compressor 1 is
switched off
(11)
the device memorises the defrosting interval count
every 30 minutes; the modification of parameter
d0 has effect from the conclusion of the previous
defrosting interval (or the activation of defrosting
in manual mode)
(12)
the display restores normal operation when, on
conclusion of evaporator fan standstill, the cell tem-
perature drops below that which has blocked the
display (or if a temperature alarm occurs)
(13)
if parameter P3 is set at 0 or 2, the device will
function as if parameter d8 were set at 0
(14)
if when defrosting is activated, the operating dura-
tion of the compressor is less than the time estab-
lished with parameter d5, the compressor will re-
main on for the amount of time necessary to com-
plete defrosting.
(15)
if parameter P3 is set at 0, the device will function
as if parameter A0 were set at 0 but it will not store
the alarm
(16)
during defrosting and dripping and when the evapo-
rator fan is stopped, the temperature alarms are
absent, provided that these were signalled after
the activation of defrosting
(17)
during activation of the door micro switch input,
the maximum temperature alarm is absent,
provided the alarm was signalled after the activation
of the input
(18)
parameters F13 and F14 have effect when the
compressor is off
(19)
parameters F13 and F14 have effect when the
compressor is on
(20)
if parameter P3 is set at 0, the device will function
as if parameter F0 were set at 2
(21)
parameters F13 and F14 have effect when the
evaporator temperature is below the temperature
established with parameter F1
(22)
parameters F13 and F14 have effect when the
compressor is on and the temperature of the
evaporator is below the temperature established
with parameter F1
(23)
the parameter can also be modified using the pro-
cedure described in paragraph 4.2
(24)
if parameter P4 is set at 0, the condenser fan will
function in parallel with the compressor
(25)
the condenser fan is off when the temperature of
the condenser drops below the temperature es-
tablished with parameter F11 on condition that the
compressor is off
(26)
if the parameter i0 and parameter i5 are set at the
same value, the effect will be caused by the acti-
vation of at least one of the inputs (until both
inputs are deactivated)
(27)
the compressor is switched off 10 sec after the
activation of the input; if the input is activated
during defrosting or when the evaporator fan is
deactivated, the activation will not have any effect
on the compressor
(28)
the device stores the alarm once the time estab-
lished in parameter i2 has expired; if parameter i2
is set at -1, the device will not store the alarm
(29)
make sure that the time established with param-
eter i7 is less than that established with parameter
i9
(30)
to avoid damaging the unit connected to the
instrument, change the parameter setting when
the device is switched off
(31)
if parameter u2 is set at 0, switching off the device
may cause the cell light and/or the auxiliary output
to switch off (the next time the instrument is
switched on the unit connected will remain switched
off); if parameter u2 is set at 1, switching off the
device will not cause the cell light or the auxiliary
output to switch off (the next time the instrument
is switched on the unit connected will remain
switched on).
(32)
the resistors are switched on when the tempera-
ture of the cell drops below the “work set-point +
u7” and are switched off when the temperature
rises above the “work set-point + u7 + 2 °C/°F”.
