Wireless system
Principles
The wireless system comprises at least two devices (e.g. CAN-EZ3 and EHS-R), which communicate
with one another, exchange data or send firmware/function data.
The wireless range is around 1000 m outdoors, and typically 30 m in buildings (through approx. 2
walls/ceilings, depending on thickness and material). Up to 3 additional wireless-capable devices
can be used as a bridge to enable data to be exchanged under deviating conditions.
RCV-DL, GBS-F and RAS-F devices cannot be used.
Pairing devices
Two steps are carried out to pair two devices:
1. Allow pairing on the target device
2. Initiate pairing on the control device
To allow pairing on the EHS-R (= target device), double clickon the button on the casing (= 2 click
within 2 seconds). Pairing is then allowed for 5 minutes (see chapter "Reset / Pairing").
On the control device, the x2 wireless ID for the EHS-R is required for pairing.
The pairing process on other devices (control device) can be found in the corresponding operating
instructions.
If a CAN-EZ3A and an EHS-R in the ATON set were purchased together, they have already been paired
at the factory.
Transmitted values
The following values are transmitted from the EHS-R to the paired device (cannot be changed):
Fault codes
If the fault code is on 0, no fault is present. For every identified fault, the corresponding number is
totalled, as explained below.
Timeout Digital value Yes/No (Yes, if wireless connection is lost)
Current output Output that is currently being consumed by the EHS-R
Higher output level Only used for internal calculation
Lower output level
Temperature 1 Temperature at sensor input 1 (PT1000 sensor)
Temperature 2 Temperature at sensor input 2 (PT1000 sensor)
HLSC temperature Temperature of sensor for high limit safety cut-out
Electronics temperature Temperature at immersion heater PCB
Fault code If faulty operation is identified on the EHS-R, the corresponding fault
code is transmitted.
Fault code Description
+1 Faulty circuit breaker
+2 Excess temperature at HLSC
+4 Excess temperature at PCB
