4.1.1 LEDs
The SEPARIX-Control CT measuring transducer is equipped with three LEDs (see
Figure 5
).
The measuring transducer lamps show different operating states and/or faults:
Power LED (green) Fault LED (yellow) Alarm LED (red)
•
blinks repeatedly 1x short if
only the interface sensor is
activated.
•
blinks repeatedly 2x short if
only the high-level sensor is
activated.
•
blinks repeatedly 3x short if
both sensors are activated.
•
OFF, whenever both sensors
are deactivated or the device
is out of operation.
•
blinks repeatedly 1x short if
there is a fault with the inter-
face sensor.
•
blinks repeatedly 2x short if
there is a fault with the high-
level sensor.
•
blinks repeatedly 3x short if
there is fault with the inter-
face sensor and the high-
level sensor.
•
blinks repeatedly 1x short if
the interface sensor signals
an alarm (max. layer thick-
ness reached/exceeded).
•
blinks repeatedly 2x short if
the high-level sensor signals
an alarm (liquid level too
high).
•
blinks repeatedly 3x short if
both sensors signal an alarm.
• OFF, when the cause of the
alarm has been rectified.
Possible causes: cable break, short circuit, sensor signal outside the per-
missible range, sensor not working, defect in the sensor evaluation of the
measuring transducer, high-level sensor tip encrusted with dirt.
4.1.2 Buzzer
The measuring transducer is equipped with a buzzer that produces an audible signal in the
event of a fault or alarm.
The acoustic signal will be turned off after pressing the acknowledge button. If desired, the
measuring transducer configuration settings allow to deactivate the buzzer so that it no
longer sounds (see section 4.2).
4.1.3 Membrane buttons
The measuring transducer has two membrane buttons:
• The red acknowledge button (4) confirms faults and alarms signalled by the LEDs
and the buzzer (also in test mode). Pressing the button switches OFF the buzzer and
the relay output returns to the normal operating state. The LEDs continue to signal
the fault or alarm condition.
•
Pressing the yellow test button (5) triggers a simulated alarm to proceed a system
test (function of the internal alarm system, the relay outputs and, where applicable,
the connected external alarm transmitters).
