If the readings need to be displayed or configured remotely, use the software, interfaces and other tools from Apator-Powogaz and follow the manuals enclosed with these products. The display of data on Elf heat meters is divided into five menu groups which correspond to the func- tionality of the data: •... - Page 15 The displayed number depends on the user configuration. If "0" is configured for the given group, the group is disabled from recording. This reading is followed by a cycled display of successive values in the record; at the beginning of each record shows a message which record will be displayed at the given moment and how many records have been registered, e.g.

7. REMOTE READING OF DATA Elf heat meters feature a connector for communication interfaces which enable remote reading and wri- ting of data. The connector also enables connection of pulse signals with additional pulse inputs, and to output the pulses generated by the heat meter to one of the output interfaces. Only interfaces from Apator-Powogaz shall be used, since they ensure proper support of the heat meter. -

Note: The pulses are output though the CMOS gate. Proper performance requires galvanically separa- ted interfaces from Apator-Powogaz. Operating the pulse output in the test (fast) mode the ma- ximum frequency of which is 64 Hz, will significantly increase the battery power consumption. If this operating mode is continuous, the battery life is reduced to approx. -

7.3. USB interface The USB communication interface enables quick and easy readouts of data from the meter, and to configu- re the available parameters. The main advantage here is that the interface requires no additional transmis- sion converters. See the separate operating manual for the instructions for driver installation and commu- nication software setup. -

8.1. Sealing Elf heat meters are sealed with self-adhesive seals to prevent unauthorised access to the electronic circuit – see the figure below. The enclosure base is sealed together with the enclosure with a sealing wire threaded through the holes in the band clip. -
Page 25: Warranty And Service
• installation or operation considered as unintented use in the user manual; • mechanical damage to the resolver enclosure. Elf heat meters self-diagnose by indication of error codes. Specific error codes are only displayed during an emergency/failure; if the error signal cause is removed, the error signal will be automatically reset. -
