French term or phrase: contrôleur présence tension moteur
"La synthèse (contrôleur permanent d’isolement -CPI-, contrôleur présence tension moteur, coupure de proximité) sera réalisée par ventilateur, en câble C2, depuis le coffret de relayage jusqu’au module déporté ou en câble CR1 si le coffret n’est pas dans la zone de mise en sécurité."
Thanks for the warning. I am sure that you are right about the general validity. In this case, the device is part of the centralised control system for ventilation fans and it seems most unlikely to me that it is really about available voltage rather than actual current. I should perhaps hedge by using the word "power".
I think that this is another case for a warning to the client that my translation assumes that the ST writer made an error.
Not for the first time in this series of questions, it seems that the author is using terms unconventionally - or downright erroneously. BD's webrefs may well be valid and relevant to the subject-matter of the ST, but 'current monitor' is most certainly NOT a valid translation of 'contrôleur présence tension moteur'.
Just as I was saying on one of your earlier questions, the confusion between voltage and current is not one that ought to be made! In my own suggestion, I went as far as 'power', but I baulk at current, which could be a quite different thing altogether. Basically, it is trickier to detect the current being drawn by a motor than to measure the voltage across it; the presence of the voltage simply means it should be turning (but is it really?) — measuring the current can give more meaningful information: zero current = either motor open circuit, or voltage not reaching it / normal current = motor probably running correctly / high current = motor probably stalled (or on fire!)
So 'voltage monitor' and 'current monitor' are, strictly speaking, 2 quite different things — though it depends on the reliability of the s/t writer as to just how precisely it was being used in the first place!
Explanation: Seems a bit of a mouthful whatever way you put it!
It's a circuit for deetcting that there is voltaae getting to the motor; we'd be more likely to say 'power' in EN (as long as your turn of phrase doesn't make it sounds as if it is actaully measuring the power being consumed by said motor).
'presence' is OK too, but a power-on (indicator etc.) is quite commonly used, and might be less clumsy, albeit slightly more informal!
I would tend to say 'monitor' rather than 'checker', as being a more commonly-used term in EN. One has to assume it is permanently monitoring the fact that power is actually reaching this motor...

Explanation: 'présence' is often translated as 'available' in this context, as here:
Control panel - All companies - [ Traducir esta página ]... status indication for control and motor power available, motor run, .... The monitor system, which adopts a continuous supervisory method that ... www.nauticexpo.com/.../control-panel-18724-_3.html - Estados Unidos - En caché

Explanation: contrôleur de la présence de la tension moteur http://www.patents.com/voltage-monitor-4879625.html
Voltage monitor according to claim 3 including timing means for timing the duration of presence of a given voltage condition respectively on said phase lead and said neutral lead.
Voltage detectors - All companies
Find all the manufacturers of Voltage detectors and contact them directly on Directindustry. ... The KD1E/15D is a digital HV potential indicator which can be used to indicate the presence of voltage or make voltage measurements on earthed neutral systems up to 15kV. ...
then the above can be changed to monitor of engine voltage presence [or motor voltage presence ]
Explanation: a variation on the general theme, it detects the presence of electrical power for some purpose; agree with Tony M about avoiding confusion with power consumed or even delivered by the motor, hence "voltage" may be right.
