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 e tension of functionalities offered by any
monitoring systems, in particular the Gas Safety System offered by Atest Gaz.
Figure 1: Location and function of the Control V controller within the Teta Gas Safety System
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 e ecution 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 e ist on the terminals of the control unit. It can
originate from another system like for an e ample ventilation system that uses one of the
output pins of control unit.

7.3 Start up
After making sure that all connections are correct it is possible to power up the device.
Upon power up all indicators of the user interface panel should be on for about 1 second. Then the device
switches to the mode of regular operation, which is indicated as e plained in Section 5.
To check whether installation of the entire system is correct it is recommended to run a comprehensive test
of the system by manual tripping of a gas alarm for the time not less than 30 seconds on any of gas
detectors incorporated into the system (the procedure of alarm tripping is described in manuals for each

specific gas detectors). After activation of the alarm procedure the control unit should indicate e ceeding of
the alarm level in a specific monitoring channel, the warning visual and sound warning devices must be
activated and the valve controller must close the gas valve.
7.4 Configuration of the controller /system
The controller configuration is carried out by setting of appropriate switches in the SW1 dip-switch unit
– see Figure 8.
Figure 8: Example of the controller configuration (address = 55, opening of DI contacts leads to valve
shutoff)
7.4.1 Address setting
The controller address ca ne set by means of switches 1...3. It is possible to set the address from 51 to 58.
7.4.2 Configuration of the DI port
Operation mode for the DI port can be selected by means of the switch 4.
Setting the switch to the ON position means that open contacts of the DI port lead to closing of a shutoff
valve connected to the controller. On the contrary, moving the switch to the OFF position makes the
controller to close the shutoff valve connected to the valve port when the contacts of the DI port are
shorted (see Figure 6).
7.5 Maintenance schedule
It is recommended to carry out scheduled maintenance of the controller after each three months of its
operation.
The scheduled maintenance includes:
visual inspection of the system and its individual components from the outside,
test of the valve operability.
7.5.1 Valve test
The controller enables manual test of the valve operation.
The reminder to initiate the valve test is activated after each three months from the last check of the valve
by regular blinking of the TEST indicator.
The test is carried out manually by the system operator from the level of the valve controller. Prior to run
the tests make sure that temporary shut off of gas supply is allowed at the moment according to operation
procedures affective for the specific gas supply system. To run the test proceed according to the following
sequence:
