4-13.2 Solenoid Valve, Release And Selection
In order to avoid accidental release of the system, it is recommended that the solenoid release
units only be fitted to the cylinder valve after the control panel has been finally commissioned
and found to operate as intended.
Note: Never attempt to relocate the solenoid valve from its mechanical position; twisting /
turning will cause the seal to break and result in a leak.
Cable(s) between the control panel and the cylinder bank should, at a minimum, be one pair
cable 1.0 sq. mm in accordance with IEC 331/332 or in accordance with the requirements for
the control installation.
Max. cable length of 246’ in order to limit power loss, max. 5% power from the panel to the coil.
It is recommended that each cable/core between the release and control panel and the cylinder
bank has a cable identification number in accordance with the wiring diagram or otherwise
agreed.
It is recommended that each core has an identification number corresponding to the terminal
number into which it is terminated.
Minimum recommended bending radius for 0.5 sq. mm single pair cable: 3.15” (80 mm)
(should always be verified against the manufacturer recommendations).
Cables should be secured to cable trays (or an alternative solid construction element) with
cable strips or other suitable means (according to normal practice)
Junction boxes supplied by others recommended having terminals suitable for up to 0.004 sq.
inch (2.5 sq. mm).
Junction boxes should be provided with an identification tag number in accordance with the
system-wiring diagram or as otherwise agreed.
