Start-Up Operation; Expansion Modules; Installation Of Modules (Fig. Iii) - Meibes heatsonic Anleitung

If the power supply fails, the backup battery (CR2032) provides the power
supply for up to 1 year. The LCD readings (on pressing button) and the date
and time are still updated, but none of the measuring functions work, incl.
the flow rate measurement. Communication still functions over the optional
M-Bus, RS485 and RS232 modules or the optical interface, but reduces the
life of the backup battery. The radio function is switched off in the event of
power supply failure.

Start-up operation

Once the meter has been installed, the components (calculator, volume measu-
ring component and both temperature sensors) must be sealed and the meter
taken into operation.
ƒ
Check the display for a plausible indication of flow rate and
temperatures.
6.

Expansion modules

The energy meter has two slots for expansion modules.
They can be mixed, but two pulse modules of the same kind must not be
installed.
The analog module occupies both positions.
These modules have no effect on consumption recording and can be fitted
retrospectively without damaging the verification mark.
The relevant ESD regulations (electrostatic discharge) must be observed.
No liability is accepted for damage (especially to electronic circuits)
resulting from failure to comply with the ESD regulations.
6.1 Installation of modules (Fig. III)
1. Open the calculator by releasing the side fasteners.
2. Lock the module into the appropriate slot and carefully connect the pre-
formed ribbon cable at both ends.
3. Close the lid and check the meter for correct operation by pressing the push
button. Renew the seal of the housing lid if the meter functions correctly.
