Commissioning A Measuring Point - INTEGRA Metering CALEC energy master Installation And Operating Instructions Manual

13 Commissioning a measuring point

An energy measuring point consists of the following peripheral equipment:
• Calculator
• Temperature sensor pair
• Flow sensor (fm)
These are matched to each other and must not be exchanged. Temperature sensors with two
wires must not be shortened or lengthened.
Procedure during commissioning: (see EN 1434-6:2007)

Protecting the measuring point
If a measuring point is used in commercial transactions, then the peripherals must be protected
against manipulation. This is done by means of a sealing wire, adhesive seal and, for the calcula-
tor, with a protected password and security caps for the screws.

CALEC energy master installation and operating instructions
• Does the installation of the sensors comply with the installation instructions?
The sensor tip should extend at least to the middle of the pipe.
• Are the sensors and the sensor pockets waterproof?
• Are the sensor version and the sensor pockets compatible? Is the the sensor
pair correctly matched (same serial
• Is the sensor type (e.g. Pt100) suitable for the calculator version?
• Is the installation side (hot, cold side) correct?
• Do the sensor heads have a 4-wire connection?
• Is the flow sensor mounted in a permitted position?
• Does the flow direction correspond to the symbol on the flow sensor?
• Does the measuring range correspond to the system flow in operation?
• Have all electrical connections been made correctly?
• Does the installation side (hot or cold side) correspond to the installation side
set in the calculator?
• Does the output signal correspond to the input signal set in the calculator
(e.g. pulse value, current range
• Do the mounting and operating locations conform to the permissible environ-
mental conditions?
• Are all cables correctly connected, and the strain relief clamps fitted cor-
rectly?
- Temperature sensor (2-/4-wire connection)
- Flow sensor
- Power supply
• Start up calculator (switch on power supply)
• Compare the flows displayed on the device and the flow sensor (if there are
two displays)
• Check temperature values (e.g. Th > Tc )
Check type of connection in the Basic settings / Pt100-input submenu and
set correctly if necessary
• Check date / time, set if necessary
• Check and set additional functions (billing dates, logger functions etc.)
