S OPERATION MODES
Radio module E-RM 30 can be in four operation modes:
•
sleeping mode
•
automatic activation mode
•
working mode
•
error mode
Description, how to cange a operation mode find in chapter 5.3. Change of operation mode.
4.1. S
LEEPING MODE
Sleeping mode is suitable for prolonged storage prior to radio module use. In this mode device does not scan
position of water meter disc (does not measure amount of consumed water) and does not trasnmit measured
data. Radio module only actualizes real time. Electronic seal is not activated and consumption of electric
power is minimized. The storage period should not exceed one year.
After installation and sealing the radio module is necessary to do an activationtivaci – description e.g.
chapter 5.3.1. Switch a radio module to the working mode.
Warning!
Without an activation, radio module E-RM 30 is not reading and sending any data.
4.2. M
ODE OF AUTOMATIC ACTIVATION
Mode of automatic activation makes installation of water meter with radio module easier. Installation consists
only from putting module on water meter and installation of mechanical seal.
In mode of automatic activation, module regulary tests disc presence. If the presence is detected, measuring
of water consumption is switched on. After 5 liters flows trough, radio module is switched to working mode
and electronic seal is activated. Date of electronic seal activation is saved to radio module memory.
We recommend to do an activation by 5 liters flow immediately after the installation. Otherwise radio module
E-RM 30 is not sending any data and it is not possible to chcek radio modules availability and functionallity
with radio reading unit.
It is also possible to do an activation by chapter 5.3.1. Switch a radio module to the working mode.
4.3. W
ORKING MODE
Radio module in working mode measures consumption of water, transmits the data in regular intervals,
actualizes real time and test state of electronic seal.
4.4. E
RROR MODE
Radio module is switched to error mode when date of billing period beginning is wrong, RAM memory
content is invalid or error occurs when saving data to flash memory. Module does not scan disc position
(does not measure water consumption), does not transmit measured data does not test state od electronic
seal. It only actualizes real time.
