5.5 General-purpose alarm

See fig. 10.
The input for external alarm (NO/NC) triggers the
alarm relay as long as it is enabled. Before the NC
option can be used, it must be enabled by setting the
DIP switch to ON (left) (pos. 15). See fig. 4.
The user can connect any alarm sensor or switch to
this input.
If the CIU unit incorporates a CIM 252 GSM/GPRS
module, an SMS message can be sent to a centrally
located SCADA system and/or directly to a mobile
phone.
If the system is connected to GRM, an SMS
message indicating a general-purpose alarm can be
sent by the GRM server, if requested.
Example 1
An overflow float switch has been installed in the
system, and it has been activated. The overflow float
switch triggers the alarm relay, and the red indicator
light illuminates, indicating abnormal operation.
The green indicator light indicating normal operation
is off. LED1 (pos. 11) flashes. The number of flashes
indicates the current alarm. See section
7.1.1 System alarms and warnings and fig. 10.
Example 2
A switch has been installed in the pit manhole cover.
If the manhole cover is open, the switch triggers the
alarm relay, and the red indicator light illuminates,
indicating abnormal operation.
The green indicator light indicating normal operation
is off. LED1 (pos. 11) flashes. The number of flashes
indicates the current alarm. See section
7.1.1 System alarms and warnings and fig. 10.

5.6 LEDs

The IO module has three LEDs.
The three LEDs are intended for use during
installation and commissioning. They are only visible
when the cover of the CIU unit has been removed.
See fig. 11.
• Red status LED (LED1) (pos. 11) for indication of
alarm.
See section 5.6.1 LED1 for indication of alarm.
• Yellow status LED (LED2) (pos. 12) for indication
of IR activity.
See section 5.6.2 LED2 for indication of IR
activity.
• Green status LED (LED3) (pos. 13) for indication
of system status.
See section 5.6.3 LED3 for indication of system
status.
During start-up, the LEDs will flash in a circular
counter-clockwise pattern for about two seconds.

5.6.1 LED1 for indication of alarm
LED1 (pos. 11) flashes red when an alarm is
generated. A special flash pattern is used to indicate
individual alarms.
See section 7.1 Grundfos alarms and warnings.
Only CIU events will be indicated by LED1.
5.6.2 LED2 for indication of IR activity
LED2 (pos. 12) flashes yellow when IR
communication has been established via the
Grundfos R100 remote control.
