NOTE 1: Master override is an input
connected via an internal relay contact to the
output when the module is not active. If
connected to an external source, the master
override input must be fused by a 1/16 A fuse.
If the master override is not connected to an
external source, then it must be connected to
common of that channel. The master override
relay transition time is typically 2 ms.
