7.7 Procedure in the event of a failure in the power
or the operating material supply
Measuring position
– If the housing is in the "Measure" position, the electrode can be moved by process pressure in
the direction of the "Service" position.
– As soon as the inductive check-back position indicator (optional accessory) can no longer
detect the end position, after 12 seconds an alarm is generated.
– The transmitter goes on HOLD.
Service position
– A loss of compressed air has no direct effect in the "Service" position.
– As soon as the EasyClean attempts to move the housing into the "Measure" position,
the inductive check-back position indicators (optional accessory) indicate an error and
after 12 seconds they generate an alarm.
– The transmitter remains on HOLD.
– The housing moves out of the process.
– As soon as power is once more available, the housing always moves into the measuring
position ("Run" appears on the display) and the transmitter moves to "Measure".
– The timers of the transmitter are reset to "0".
– Not detectable without flow sensor (optional accessory).
– As an option the EasyClean generates an alarm if no liquid can be detected after 12 seconds.
– This message remains until the EasyClean is reset (press "In/Out" and "Water" buttons
simultaneously).
– Calibration cannot be initiated unless a medium is detected.
– A relevant measurement is continued.
