 8. Do not insert the control modules at this time.
Proceed to the MCS-166/MCS-208 start-up
section of this manual.
System Start-Up and Adjustment
MCS-166/MCS-207/Transducer
The MCS-207 is factory calibrated for a 4-20 ma output
to drive the transducer. However, other DC current
ranges or DC voltages ranges can be selected for
output. Consult factory if a transducer with a different
input range has been selected.
Generally, the only MCS-207 adjustments necessary are
the Dancer Position and the Gain controls found on the
front panel. On the transducer, the zero and span may
also have to be adjusted.
The start-up and adjustment procedure which follows
will provide a stable operating system.
Refer to Figure 12, page 17, for exact location of
internal adjustment potentiometers.
A. Preliminary Set-Up
 1. Set voltage selector switch on MCS- 166 for
proper input voltage range. This will be
either 120 VAC or 220/240 VAC.
NoTe: An additional switch has been added to the
MCS-166 for selecting 220 or 240 VAC operation. This
switch is labeled Low-High.
 2. Set the Low-High Switch as follows:
 a. For 120 VAC, set to High Position
 b. For 240 VAC, set to High Position
 c. For 220 VAC, set to Low Position
NoTe: The Low-High switch is used primarily for
selecting 220 or 240 VAC operation when the line
selector switch is set for 240 VAC, but it can also be
used when low line voltage exists.
 3. Low line input: For 108 VAC input when
set on 120 VAC or for 198 VAC input when
set on 240 VAC, set the Low-High switch to
the Low Position.
 4. High line input: For 132 VAC input when
set on 120 VAC or for 268 VAC input when
set for 240 VAC, set the Low - High switch
to the High Position.
Improperly setting the 120/240 VAC
Selector Switch and the High-Low Selector Switch
can damage the power supply and/or control
Module and void their warranties.
 5. Slide the power module into the housing
and secure with the two captive fasteners
on the faceplate.
Pull the ribbon cable forward so
that the connector end is in front of the housing
assembly. Fasten the ribbon cable connector to
the pin connector on the control module. Pin 1 (red
tracer) on the ribbon cable must connect to pin 1 on
the control module as shown. This “Red Tracer” will
ALWAYS be toward the top of the control.
