Inputs and outputs
4.1
Input functionality
The circuit board supports up to three configurable dry contact digital inputs. These inputs
are configurable via the corresponding i#F parameter.
4.1.1
Digital input table
An alarm is generated after a parameter delay did from the
activation of the input; the message EA is displayed and the
status of the outputs is not changed. The alarm reset is
automatic as soon as the digital input is switched off.
A lockout alarm is generated after a parameter delay did from
the activation of the input; the message CA is displayed and
the control relay outputs are deactivated.
The alarm reset is automatic as soon as the digital input is
switched off.
If a number of pressure switch trips equal to the parameter
nPS is reached within the time period set by parameter d#d ,
the alarm is triggered.
The message PA is displayed, the compressor is switched off
and adjustment is suspended. To resume normal operation, the
instrument must be switched off and on again. When the input
is active, the compressor is always switched off.
It signals the device to open the cold room door. When the
door is opened, the compressor and fans regulate according to
the value of the odc parameter. After the time set in
parameter d#d, the door open alarm is activated, the message
dA” appears on the display. After the alarm signal and the time
indicated by the parameter rrd, adjustment resumes. In the
open door situation, the high and low temperature alarms are
disabled. Furthermore, after the door is closed, the cold room
light remains on for one minute (function cannot be changed).
The alarm returns automatically as soon as the digital input is
switched off.
Starts a defrosting cycle if conditions are right.
When the digital input is activated, the auxiliary relay is also
activated. When the digital input is switched off, the auxiliary
relay is also switched off.
Allows the light output to be switched on or off by activating
the digital input
When the digital input is activated, the instrument is switched
off. When the digital input is switched off, the instrument is
switched on.
Enables the control mode to be reversed from cold action to
hot action
During the energy-saving cycle, the set point is increased by
the value contained in HES so that the operating set point
becomes SET+HES. Naturally, the operating set point must be
such that it complies with the regulations governing product
preservation. The energy-saving cycle continues as long as the
input remains active.
