1 General information
The Control V device is a local controller for a gas shutoff valve. Its location within close vicinity of the valve
and a built-in rechargeable battery make it possible to avoid many problems related to voltage drops down
long electric cables and conductors.
The valve can be controlled by means of a binary signal (DI) or via the Teta data transmission interface. It is
why the valve controller of Control V type perfectly enables extension of functionalities offered by any
monitoring systems, in particular the Gas Safety System offered by Atest Gaz.

1.1 Operation principle
Upon receiving a command via the Teta data transmission interface or a digital input (DI) the Control V valve
controller produces a waveform necessary to shut off a valve.
Operation of the controller is subjected to continuous monitoring of its operability and its key parameters,
where such items as continuity of the line for valve control (its resistance), charging status of the embedded
battery and level of power voltage are checked on-line in the automatic mode.
The Control V unit also reports a need to test the valve and enables manual execution of such a test – see
details in Section 7.5.1.
2 Safety
All activities related to connecting detectors, signallers and other system components must
be carried out while Control Unit's power supply is off.
Although switching power supply of the Gas Detection and Safety System off, there is
a possibility that a dangerous voltage can exist on the terminals of the control unit. It can
originate from another system like for an example ventilation system that uses one of the
output pins of control unit.
