FLOW EXPANSION
A2C-F3 ow expansion modules add 3 additional ow inputs
to the controller. These modules may only be added to the
lower right module slot, one per controller, and it is the only
module that will t in this slot.
The ow expansion module has DC voltage and polarity,
and the + or red connection from the ow sensor must be
connected correctly to the + (positive) terminals on the
module. Finish ow expansion in the Devices, Flow Sensors
menu aer installing the module.
WIRE TIE HOLDERS
Wire tie holders are molded into the lower back of the wiring
compartment to secure eld wiring with plastic “zip” ties.
This provides a strain relief to keep eld wires from pulling
downward on the modules, and keeps the inside neat and
organized.
Additional wire tie holders are provided near the Power Supply
Board for sensor and other connections.
TRANSFORMER FUSE
The transformer uses a replaceable 5 x 20 mm electrical fuse,
located next to the convenient on/o switch. Two spare fuses
are stored in the bottom rear of the facepack frame.
Replacement fuses shall be glass body 5 x 20 mm 250V, 2A
fast blow, commonly available wherever electronics are sold.
OPTIONAL WIFI OR LAN
The Wi-Fi or LAN slot allows installation of optional
communication modules.
