No Controls (relays, etc.) should be
mounted in the Smart Panel enclosure
or connected to power supplies in the
control panel. Additionally, control
wiring not connected to the Smart
Panel should not be run through the
cabinet. This could result in nuisance
faults.
Any inductive devices (relays) wired in
series with the flow switch for start/
stop, into the Alarm circuitry, or pilot
relays for pump starters wired through
motor contactor auxiliary contacts
must be suppressed with YORK P/N
031-00808-000 suppressor across the
relay/contactor coil.
Any contacts connected to flow switch
inputs or BAS inputs on terminals 13
- 19 or TB3, or any other terminals,
must be suppressed with a YORK P/N
031-00808-000 suppressor across the
relay/contactor coil.
Control wiring connected to the con-
trol panel should never be run in the
same conduit with power wiring.
