6.3.2 Shutting down the plant
"Blockage" and "Steam Leakage" faults may be indicated at different times when the plant
is shut down. Depending on the type of steam trap or the plant operating conditions,
condensate may (re-)accumulate in the test chamber so that only "Blockage" is indicated.
These status indications are interpreted as faults and stored by the PLC software!
6.3.3 Recommendation
We recommend connecting the CONA
®
-control system to the plant control, so that the plant
control evaluates all fault indications and sets the "Trap Inspect" LEDs. This permits faults
that are indicated when parts of the plant are started up or shut down to be reliably
suppressed.
The outlet 1 must be set to Slave 1A in the plant control for this purpose,
(from Software version 1.8).
At this outlet the PLC-control of the ASI-/Profibus Gateways detects, that the LEDs „Trap
Inspect“ should be set by Bus. The PLC-control saves no errors, respectively old errors are
not blinking.
7.0 Care and maintenance
The CONA
®
-control monitoring system is practically maintenance-free and regular
maintenance at fixed intervals is not necessary.
Remove any dirt from the sensor and the test chamber occasionally, depending on the
operating conditions.
Never clean electronic components using liquids or aggressive solvents or agents that are
detrimental to health or highly flammable.
We recommend dampening a cloth with cleaning agent rather than applying it directly.
No liquid must be allowed to come into contact with or get inside the electronics.
NOTE !
- Please make a note of all indicated faults prior to shutting down the plant or part
of the plant, because shutting down the plant may cause certain faults to be
indicated even though they did not occur in normal operation.

ATTENTION !
The power supply cable must be disconnected from the mains (i.e. de-energised)
prior to cleaning the electronics. Suitable precautions must be taken to prevent
the mains voltage from being re-connected inadvertently.
Non-observance can result in death, severe personal injury or substantial
property damage.
