7. Special features of system setup
The setup of all probes is the same. However, due to the system setup there are 3 differently
weighted types of use of the probes.
Water level limiter probes: If desired, probes can be defined as water level limiter
probes. These then switch the alarm output. Both low-
water level monitoring and high-water level monitoring
are possible (
observe local regulations! ).
“Control probes”:
These probes are for enabling a switching function via
(assigned) a relay output (pump control, horn, or such like).
Water level probes: These probes display via their state (submerged /
(not assigned) emerged) only the current fill level.
Note the system reaction to state changes (also errors) of individual
probes as described in Chap. 4.2.
8. Commissioning
Commissioning and maintenance must be carried out by qualified
personnel! If no sufficiently qualified person can be employed, IGEMA
GmbH can be commissioned to carry out the commissioning. In principle
IGEMA GmbH recommends commissioning the indicator at the same time
as the boiler (point 8.3). If it is not possible to commission the indicator
according to point 8.3, the indicator can be commissioned with the boiler under
pressure and temperature (point 8.4)
All liquid level gauges are subjected to 100% pressure testing before delivery. In individual
cases, material settling may occur during transport, longer storage or during assembly. All
screw connections must therefore be checked for tight fit and appropriate torque.
8.1 System setup
- Regulation-compliant assembly of the water column at the boiler.
- Electrical connection as in Chap. 5.
- System planning
e.g. with system / assignment table (in correct operating state)
from the attachment to these mounting and operating instructions
- Programming as in Chap. 6
