8.5.1.1 Description of system alarms
Alarm
Description
Overflow
The alarm is displayed if an analog level sensor or a float switch registers an overflow.
High level
A high level can be set to activate an alarm relay. When the high level is reached, the system attempts to
start both pumps. High level must always be the highest level in the system.
Alarm level
An alarm level can be randomly selected. Enables interlock.
Dry running
The dry-running level can be randomly set as the lowest level in the system. When the dry-running level
is reached, both pumps are stopped. The foam-draining level ignores the dry-running alarm and the
system pumps down to the foam-draining level.
Float switch
The warning is displayed in the event of a discrepancy between the input signals from the various float
switches, for example, if the float switch "Start" is enabled and the float switch "Stop" is disabled in a
wastewater pit.
Level sensor
The alarm is displayed if the level sensor input is outside the measuring range.
Conflicting levels
The alarm is displayed if the signal from the analog level sensor does not correspond to the float
switches. This situation may occur if the level sensor is damaged or clogged. If the dry-running float
switch displays dry running without the level sensor having displayed dry running, or if the high-level float
switch is enabled without the level sensor also displaying high level, the system considers the level
sensor to have failed and disregards it.
If this situation occurs, it is possible to continue with only a high-level float switch and a dry-running float
switch. When the high-level float switch is enabled, the pumps that are allowed to start will start pumping
for a preset period of time or until the dry-running float switch displays dry running.
Note:
If the analog sensor is damaged, "Dry running" and "High level" appears in the display even if the
alarms have not been set to "Enabled".
Note:
If the analog sensor is damaged, "Conflicting levels" appears in the display even if the alarms "High
level" and "Dry running" have not been set to "Enabled".
Flowmeter
The warning is displayed if the flowmeter input is outside of the measuring range.
Power meter
The warning is displayed if the power meter input is outside of the measuring range.
User-defined relay output
activated
The alarm is displayed when a relay is manually controlled.
Hardware fault
Hardware fault in a system module.
External fault
Indicates an external fault registered via a digital input.
Mains supply fault
A mains supply fault can be displayed if an emergency power supply module is connected. No power
supply to the system.
Battery backup (UPS)
The alarm is displayed if the emergency power supply can no longer power the system.
Communication fault (IO 351B)
The alarm is displayed if there is no GENIbus communication with the IO 351B. The system does not
control/read the digital or analog input and output signals of the module.
CIM module fault
Indicates a CIM module fault.
SCADA callback error
The alarm is displayed if there is a modem communication fault.
Ethernet, no IP address from
DHCP
No IP address assigned by a DHCP server.
Ethernet disabled due to misuse
The Ethernet shuts down as protection against incorrect use.
SIM card fault
Faulty SIM card. The SIM card is inserted in the CIM module.
User-defined sensor 1
The sensor is faulty.
User-defined sensor 2
The sensor is faulty.
User-defined sensor 3
The sensor is faulty.
Pressure sensor, discharge line
The pressure sensor installed in the discharge line is faulty.
Extra fault 1 to 4
User-defined,external faults registered via a digital input.
Gas detector
Gas detector active.
Water on pit floor
There is water on the floor in the pump pit.
8.5.2 Pump alarms
This display shows the parameters defined as pump alarms.
Select the parameter to be monitored, and set it as desired.
Pump alarms can be triggered by two fault types:
•
Analog fault. See section about analog fault configuration. An analog fault trips an alarm if its value lies outside a set limit.
•
Digital fault. See section about digital fault configuration. A digital fault trips an alarm if a fault occurs (on/off).
