CAUTION
The speed controller includes safety devices which, in the event of defects, may cause the speed controller to stop and thereby
stop the motor. This motor can itself sustain stoppage by a mechanical lock. Finally, voltage variations, in particular power cuts,
may also cause stoppages to occur.
The disappearance of causes of stoppage could cause restarting, dangerous to some machines or installations, in particular those
which must be in conformity with the decrees relative to safety.
Therefore, in such cases, the user must take stepsagainst such possibilities of restarting, more particulary by the use of a low
speed detector which, in the event of an unprogrammed stoppage of the motor, will cut off the speed controller supply.
The equipement design must be in conformity with the prescriptions of standard NFC 15-100.
More generally, any action, whether on the electrical part or the mechanical part of the installation or machine,must follow the cutoff
of the speed controller power supply.
NOTE
This type of RECTIVAR is equipped with V3 - version software.
It can replace V1 - or V2 - version RECTIVARs with the following conditions :
1- RECTIVAR requiring the "vertical motion" cartridge :
use cartridge VW2-RLD221 which is the only one that is compatible with V3 -.
2- For installations controlled or monitored via a serial link other RECTIVARs using
V1 - or V2 - : version software : use software which corresponds to the RECTIVARs
already installed.

Frequently Answers and Questions
What is the maximum armature voltage for these controllers?
The recommended armature voltage is ≤ U mains x 1.05 with the RTV84 and ≤ U mains x 1.16 with the RTV74.
How can I adjust the acceleration and deceleration ramps?
Acceleration and deceleration times are separately adjustable from 0 s to 999.9 s.
What are the different operating modes available?
The controllers offer continuous duty operation, standard cyclic operation with time limits, and particular cyclic operation for specific cycles.
