How to replace a JRI digital probe while a maintenance action or a calibration by replacement of probe?

To guarantee the tightness and the functionalities of the connector, you have to follow some steps while replacing the probe.
1/ Unscrew only both central wheels which connect the extension lead to the probe. One has to be unscrewed upwards and one downwards.
2/ Wait for the SPY RF recorder to detect that the probe has been unplugged. Once detected, dashes appear on the screen of the recorder. On www.siriusweb.fr, you can see the mention «default sensor» appearing. It shows that the recorder has detected that the probe has been unplugged.
3/ Screw the new digital probe with the central wheels.


Reminder: Don't let Ice appear on the connector and the probe. It could damage the probe and modify temperature values.

 

I see a gap between my cold room indicator and the SPY RF recorder temperature, what could I do?

Two possible reasons for that situation:

  • SPY RF records 1 measuring point every 15 minutes. The screen is not refreshed in real time (On the contrary the indicator of the cold room is refreshed in real time), the displayed value on the SPY can have been measured 15 minutes sooner.
  • The JRI probe and the regulation probe of the cold room are not situated at the same place.

If the gap is noticed on a period of a minimum of 15 days, the second reason is most probable. JRI places the probe at the return air which is the hottest point of the cold room.


To sweep aside doubts on the accuracy of measurement of the JRI probe, we recommend switching the JRI probes from two cold rooms following the steps of the procedure of replacement of a probe:

  • If the gap noticed is the same, the probe accuracy can not be the reason. The value gap is indeed due to the location of both probes. In that case, you can ask your installer to adjust the regulation probe of the cold room.
  • If the probe replacement reduces consequently the gap between the measurements of the regulation probe and the JRI probe, the support department of JRI can help you to define a maintenance action.


My negative cold room often displays positive temperatures which triggers threshold alarms sometimes. Is it normal?

During defrosting cycles of the negative cold rooms, temperature, behind the evaporator, increases a lot in a short time (defrosting peak).
This situation is normal.
The place of the JRI probe allows checking the evaporator functioning properly (quality and frequency of defrosting cycles).
If the alarms are triggered during defrosting cycles, ask your installer to modify the settings of your compressor and never let the door opened too long.

 

Is it normal that the data are not updated on SiriusWeb platform while recordings are set every 15 minutes?

This is normal and depends on the frequency of sending data between the recorder and the SiriusBox. However, do not worry because the alarms are sent in real time.

 

I get the message "Lo Bat" on the SPY RF. Is my SPYRF recorder still saving data?

This message indicates that the battery of the recorder is at its end of life. The recorder will continue to record until the battery is not completely discharged. This duration depends on the settings of the device. As soon as this message appears, you must replace it. If you do not have spare batteries, you can order them from our service by sending your request directly at sales@jri.fr.

Are alarms sent in real time by SiriusBox?

Yes, SPY RF recorders are working in the same way, alarms are directly sent in real time to Sirius Box that forwards it to the platform.

Does the GPRS system generate an adding delay?

No, GPRS is permanently open and send information as soon as the SiriusBox receive it.
