Wireless Measuring Module ECOLOG-PRO 4MAR (EN)
Wireless Measuring Module 4-20mA - ECOLOG-PRO 4MAR
ECOLOG-PRO 4MAR 868 MHz, art. no. 802475 / ECOLOG-PRO 4MAR 915 MHz, art. no. 802487 / ECOLOG-PRO 4MAR 922 MHz , art. no. 802561
Module
The measurement module fulfills 2 functions:
Power supply for the connected sensors.
Measure and save the measurement values.
ID number
The ID number is used to identify the module in elproMONITOR.
Status indicator 1; module activity
Left LED green blinking every 10 seconds; Connection OK
Left LED red blinking every 10 Seconds; No connection
Left LED orange blinking; in pairing state
Left LED dark; no power supply
Left LED => light up red with 1s dark phase each 10s, Right LED => light up red 1s dark phase each 10s; ECOLOG-PRO 4MAR module entered Fail-safe State. Note: Fail-safe Mode initiated when powers supply voltage < 18V.
In Fail-safe State measuring and communication is suspended on the module. To chage back to normal state, un-plug the device, wait for one minute and plug again.
Status indicator 2; sensor status
Radio connection to the measuring modules
Condition | Description |
|---|---|
