Installation Instructions

Micropilot FWR30
Endress+Hauser 5
Output
Output signal
Cellular radio NB-IoT, LTE-M with 2G fallback
• 2G GPRS/EDGE
• 4G LTE-M1 (LTE Cat-M1)
• 4G LTE-NB1 (NB-IoT)
The cellular radio signal is selected automatically by the device. The selection depends on availability.
The priority is 4G (LTE-M1 or LTE-NB1). If neither of the two cellular radio signals is available, the
2G (GPRS or EDGE) cellular radio signal is selected.
Transmission interval
15 minutes to 24 hours.
The battery life depends on the transmission interval.
Protocol-specific data
The FWR30 uses
• internet protocol TCP/IP and the secure transport layer TLS (v1.2)
• application layer protocol HTTPS
Power supply
Supply voltage
Replaceable battery, standard size, lithium (D), 3.6 V, 19 Ah (included in the delivery)
Designation in accordance with IEC: ER34615 (primary battery lithium thionyl chloride); product
recommendation: Tadiran SL-2880
The measuring device determines the battery charge state automatically. The LED flashes red
every 10 seconds if the battery charge state is low or critical.
Safety notice for the device battery
L
CAUTION
Risk of fire or burns if the device battery is handled incorrectly!
‣
Do not charge or open the battery, expose it to fire or heat it above 100 °C (212 °F).
‣
Only replace the battery with a ER34615 battery (lithium-thionyl chloride primary battery, size
D). The use of any other battery can present a fire or explosion hazard.
‣
Dispose of the used battery immediately as per national regulations.
‣
Keep used batteries out of the reach of children. Do not open used batteries or expose them to
fire.

4) Calculation only applies to TADIRAN SL-2880 battery at approx. +25 °C (+77 °F). A strong cellular radio
signal is required. The actual battery life can vary greatly and depends on a number of factors including the
network provider, temperature or humidity. High transmission rates reduce the battery life.
