Figure 32: Parameter list example (i08)
– Acknowledge and save change of value of a param -
eter.
– To exit from the Parameter list and return to the
display of opening degree (OD), keep the push button
activated for 2 s.
• Display (see Figure 30 )
– Normally the opening degree (OD) 0 % to 100% of
the ICM valve is displayed. No activation of push but-
tons for 20 s means that the display always shows
OD. See the following figure.
Figure 33: Parameter list example (OD)
• Displays the parameter.
• Displays the actual value of a parameter.
•
Displays the function status through text (see Figure 30 ).
– Mod represents that ICAD is positioning the ICM
valve according to an analog input signal (Current or
Voltage).
– Low represents that ICAD is operating the ICM valve
like an ON/OFF solenoid valve with low speed ac-
cording to a digital input signal.
– Med represents that ICAD is operating the ICM valve
like an ON/OFF solenoid valve with medium speed
according to a digital Input signal.
– High represents that ICAD is operating the ICM valve
like an ON/OFF solenoid valve with high speed ac -
cording to a digital input signal. See Figure 34 .
Figure 34: High speed status
Alarms - ICAD can handle and display different alarms.

Figure 30: ICAD
Industrial control actuator with display (ICAD) is equipped
with a man machine interface (MMI) from which it is pos-
sible to monitor and change the setting of parameters to
adapt the ICAD and the corresponding
motorized industrial
control valve (ICM) to the actual refrigeration application.
Set parameters using the integrated ICAD MMI (see Figure
30 and 31 ), which consists of the following:
• Down arrow push button (see Figure 30 )
– Decreases parameter number by 1 at each activation
• Up arrow push button (see Figure 30 )
– Increases parameter number by 1 at each activation
Figure 31: ICAD MMI
• Enter push button (see Figure 30 )
– Gives access to the Parameter list by keeping the
push button activated for 2 s. A parameter list ex-
ample, parameter
i08
, is shown in Figure 32 .
– Gives access to change a value after accessing the
Parameter list.
