Watlow Dual DAC - Manual

WATLOW DAC User’s Guide 1
Introduction
The Digital to Analog Converter (DAC) is
an optional module for Watlow Anafaze
controllers. It is used to convert the con-
troller’s Distributed Zero Crossing (DZC)
output signal to an analog process control
signal. Each DAC supports 4 to 20 mA, 0 to
5V and 0 to 10V output signals. This man-
ual contains installation instructions, con-
figuration information, and specifications.
Installing the DAC
You will need the following tools:
• Power drill with 0.15 inch bit
• Screwdriver
• Four screws up to #6 size. Choose
screws appropriate for your panel
material.
• Wire strippers
To install the DAC module:
• Choose a wall or panel to install the
DAC.
• Drill four holes for mounting screws.
Refer to Figure 1 for mounting hole
dimensions and placement.
• Place the DAC in its mounting location
so that the holes in the DAC line up
with the holes you have drilled. Insert
the screws in the holes and tighten.
• Shut the system power off and wire the
DAC to the controller and final control
element. Figure 2 shows the wiring for
current. Figure 3 shows the wiring for
voltage.

Warranty
The DAC is warranted to be free of defects
in material and workmanship for 36 months
after delivery to the first purchaser for use,
providing that the units have not been mis-
applied. Since Watlow has no control over
their use, and sometimes misuse, we cannot
guarantee against failure. Watlow’s

are limited to replacement, repair, or refund
of purchase price, and parts which upon
examination prove to be defective within the
warranty period specified. This warranty
does not apply to damage resulting from
transportation, alteration, misuse, abuse, or
improper fusing.
