Min function: with the Min function the lower threshold is the tripping threshold and the upper threshold is the resetting
threshold. The threshold is activated after the set delay when the value of the selected measurement is under the lower
limit. Reset is activated after the set delay when the value of the measurement is higher than the upper threshold.
Max function: with the Max function the upper threshold is the tripping threshold and the lower threshold is the re-
setting threshold. The threshold is activated after the set delay when the value of the selected measurement is higher
than the upper limit. Reset is activated after the set delay when the value of the measurement is lower than the lower
threshold.
Min+Max function: with the Min+Max function both the upper and the lower thresholds are intervention thresholds.
The threshold is activated after the respective delays when the value of the selected measurement is either lower than the
lower limit or higher than the upper limit. Resetting is immediate as soon as the value returns within the limits.
• Tripping may mean energising or de-energising the LIMn limit according to the setting.
• If the LIMn limit is set with memory, manual resetting is possible using the specific control in the command menu.
• See the M15 settings menu.

Remote variables (REMx)
• The ref. 422684 can manage up to 16 variables controlled remotely (REM1…REM16).
• The state of these variables can be edited as reuired by the user by means of the communication protocol and may be
used in combination with outputs, Boolean logic etc.
• Example: a relay using the control software can be freely activated and deactivated by using a remote variable (REMx)
as source of an output (OUTx). This would allow to use ref. 422684 422684 output relays to control loads, e.g. lighting or
other.
• Another use of the REM variables may be to enable or disable given remote functions by inserting them in a Boolean
AND logic with inputs or outputs.

User alarms (UAx)
• The user can define up to 8 programmable alarms (UA1…UA8).
• The following can be established for each alarm:
- the
source
, i.e. the condition which generates the alarm;
- the
text
of the message which must appear on the display when the condition occurs;
- the
properties
of the alarm (like for the standard alarms), i.e. so as to interact with the genset control.
• For example, going beyond a threshold may be a condition which generates the alarm. In this case, the source must be
one of the LIMx limit thresholds.
• If instead the alarm must be displayed as a conseuence of the activation of an external digital input, then the source will
be an INPx.
• The same criterion can be used to combine an alarm to complex conditions resulting from the logical Boolean combi-
nation of inputs and thresholds, etc. The PLCx variables will be used in this case.
• The user can defined a freely programmable message which will appear in the alarm pop-up window.
• Properties can be defined for the user alarms using the same method applied for normal alarms. In other words, it is
possible to determined whether a given alarm must stop the motor, sound the siren, close the global alarm output etc.
See the Alarm properties chapter.
• Multiple simultaneous alarms will be displayed in seuence and the total number of alarms will be shown.
