INSTALLATION INSTRUCTIONS
Station Valve Installation
Up to two 24 vac solenoid valves can be connected to each station output and wired
back to the Common (COM) connector. When using long runs of cables, be aware
that voltage drop can play a significant roll, especially when more than one coil is
wired to a single station. As a good rule of thumb select your cable as follows:
0–50m
cable dia 0.5mm
50–100m cable dia 1.0 mm
100–200m cable dia 1.5mm
200–400m cable dia 2.0mm
When you are using multiple valves per station the common wire needs to be much
larger as it needs to carry more current. In these circumstances choose a common
cable 1 or two sizes larger than required. When making connections in the field, only
ever use gel filled or greased filled connectors. Most field failures occur due to poor
connections. The better the connection here, and the better the waterproof seal the
longer the system will perform without trouble.
