4.9.1 Enter Program Changes: Refer to the Programming
Sheet for Control Panel & Modules in the panel drawing if
it is available. If not, Refer to Figure 4.2 for Sample
Programming Worksheet. Ignoring the alarm messages
and lights, enter all required user setup changes. The
Program Enable edit box in MR100 for Windows CE or
Program Enable dip switch on the MR100/ML100 Inter-
face Module must be set to ENABLE to allow program-
ming. Refer to Figure 2 in Appendix G, or Figure 5.9 for
ML100 Dedicated Interface Module, or Figure 5.10 for

4.9.2 Turn On Heater Power: Close the circuit breakers
for all heat trace circuits controlled by the MasterTrace
control panel.
4.9.3 Respond to Alarm Conditions: Examine each alarm
condition and correct problems as required. High Current
and Low Temperature alarms should be ignored during
start-up and until normal operating levels have been
reached. Refer to Appendix C: Summary of Alarms and
Causes for information on potential causes of alarms.
4.9.4 Check Actual Readings: Once the system has
reached normal operating temperatures, check the
individual temperature, current and ground fault current
readings against expected values for each circuit. This can
indicate wiring or design errors.
4.9.5 Check the RTD Wiring: Locate and open the
junction box or head of the selected RTD. Either
disconnect the RTD or short the wires. The RTD Short or
RTD Open alarm will be displayed on the Interface
Module showing the Heater Name. Confirm that the
displayed heater matches the heater of the selected RTD.
