480V Electrical Circuits

For 480V electrical supply, a 480V to 240V step-down
transformer must be installed by a qualified electrician.
Transformer Sizing
For single-phase power, 480V to 240V transformer
24U169 (purchase separately) may be used. See Sin-
gle-Phase 480V to 240V Transformer, 24U169 on
page 107.
Minimum transformer rating can be calculated by taking
output voltage times the ADM setting.
Single Phase, 20A ADM Breaker Setting Example:
240 volts x 20 amps = 4800 watts
Three Phase, 20A ADM Breaker Setting Example:
240 volts x 20 amps x
208V Electrical Circuits
For 208V electrical supply, a qualified electrician can
install a 208V to 240V step-up transformer to improve
startup times.
Transformer Sizing
Minimum transformer rating can be calculated by taking
transformer output voltage times the ADM breaker set-
ting.
Single Phase, 20A ADM Breaker Setting Example:
240 volts x 20 amps = 4800 watts
Three Phase, 20A ADM Breaker Setting Example:
240 volts x 20 amps x SQRT(3) = 8315 watts

Select ADM Settings

NOTE: See Appendix A - ADM on page 111 for
detailed ADM information, including general operation.
1. Turn main power switch ON
2. When the ADM is finished starting up, press
to switch from the Operation screens to the Setup
screens. Use ,

3. On the System 2 screen:
a. Check the box in the "Installed" column for each
channel that has a heated hose and gun
installed.
b. Select the RTD type used on each installed
gun. See gun manual.
NOTE: An incorrect RTD setting will cause the system
to be incapable of maintaining the temperature setting.
NOTE: The supported RTD types are Ni, 100 ohm; Ni,
120 ohm; NiFe, 604 ohm; Pt, 100 ohm (385), Pt,
100 ohm (392); and Pt, 1000 ohm. An "Auto" selection is
available but should only be used when the specific
RTD type cannot be identified. Using the "Auto" RTD
setting may result in inaccurate temperatures.
To prevent fire and explosion, a qualified electrician
must determine the proper circuit breaker size to use
for the power supplied to the system.
4. On the System 3 screen:
a. Enter the main circuit breaker size used. This is
the circuit breaker installed external to the sys-
tem for the system power supply.
