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 114 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 ,
between screens.
3. On the System 2 screen:
a. Check the box in the "Installed" column for each
channel that has a heated hose and applicator
installed.
b. Select the RTD type used on each installed
applicator. See applicator manual.

, , and to navigate
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.
NOTE: The InvisiPac system limits the amount of power
it pulls based on the input circuit breaker size. This
impacts the startup times because it affects the heating
energy used to warm up the materials.
5. On the Advanced 1 screen, set the system date and
time.
