Chapter 8 Service & Testing
• If the new module has not been programmed according
to the Programming Sheet for Control Panel or
Modules, then complete at this time following the steps
in Chapter 6.
8.3.6 Replacing an MS-1 or MS-2 External Switching Mod-
ule: Before proceeding, check that all wires connected to
the module are correctly labeled. Check that the Program-
ming Sheet for Control Panel or Modules correctly reflects
the configuration of the module. The replacement control
module can be programmed before it is placed in the control
panel by connecting a 120 Vac supply to its power input
terminals and following the steps in Chapter 6. Complete
the following steps.
• Turn off power to the Control Module and all affected
heater circuits.
• Disconnect all wires to the Control Module. Refer to Fig-
ure5.2 or Figure 5.3.
• Remove the four Nylock nuts that secure the Control
Module to the back plate and remove the module.
• Repeat the above steps in reverse order to install the new
module.
• If the new module has not been programmed according
to the Programming Sheet for Control Panel or Modules,
then complete at this time following the steps in Chapter
6.
8.3.7 Replacing an MS-5 or MS-10 Module with External
Switching: Before proceeding, check that all wires connected
to the module are correctly labeled. Check that the Program-
ming Sheet for Control Panel or Modules correctly reflects
the configuration of the module. The replacement control
module can be programmed before it is placed in the control
panel by connecting a 120 Vac supply to its power input
terminals and following the steps in Chapter 6.
Complete the following steps.
• Turn off power to the Control Module and all affected
heater circuits.
• Disconnect all wires from the Control Module. Refer to
Figure 5.4.
• Remove the four Nylock nuts that secure the Control
Module to the back plate and remove the module.
• Repeat the above steps in reverse order to install the new
module.
• If the new module has not been programmed according
to the Programming Sheet for Control Panel or Modules,
then complete at this time following the steps in Chapter
6.
8.3.8 Replacing the ML100 Dedicated Interface Circuit Board
Assembly or Keypad: Before proceeding, check that all wires
connected to the module are correctly labeled. Complete
the following steps.
• Turn off power to the Control Module which is connected
to the ML100.
• Disconnect the ribbon cable from the Interface Module.
• Remove the four Nylock nuts, labeled “A” in Figure 5.9
that secure the Interface Circuit Board Assembly.
• Disconnect the ribbon cable connector to the Keypad
and remove the Interface Circuit Board Assembly.
• Replace the ML100 Dedicated Interface Circuit Board
Assembly with Nextron part number 1303-0002_2.
• To replace the Interface Keypad, insert a small blade screw-
driver between the bezel and a corner of the keypad as
shown in Figure 5.8. Pry the Keypad up and pull off.
Clean any residual adhesive with a solvent. Replace with
Nextron part number 1002-0001_1. Remove the adhesive
backing from the Keypad, insert the ribbon cable through
the slot and press the Keypad into place.
• Repeat the above steps in reverse order to complete the
installation.
8.3.9 Replacing an MR100 Group Interface Circuit Board
Assembly or Keypad: Before proceeding, check that all wires
connected to the module are correctly labeled. Check that
the Programming Sheet for Control Panel or Modules cor-
rectly reflects the selected modules. Complete the following
steps.
• Turn off power to the Interface Module.
• Disconnect all wires from the Interface Module.
• Remove the four #6-32 machine screws, labeled “A1” in
Figure 5.10 that secure the Interface Module housing
and remove the housing.
• Remove the four Nylock nuts, labeled “A1” in Figure
5.11 that secure the Interface Circuit Board Assembly.
• Disconnect the ribbon cable connector to the Keypad
and remove the Interface Circuit Board Assembly.
• To replace the MR100 Group Interface Circuit Board As-
sembly use Nextron part number 1304-0001_5.
• To replace the Interface Keypad, insert a small blade screw-
driver between the bezel and a corner of the keypad as
shown in Figure 5.8. Pry the Keypad up and pull off.
Clean any residual adhesive with a solvent. Replace with
Nextron part number 1002-0001_1. Remove the backing
from the Keypad, insert the ribbon cable through the slot
and press the Keypad into place.
• Repeat the above steps in reverse order to complete the
installation.
• Program the selected Control Modules for communica-
tions.
8.3.10 Replacing an MR100 for Windows CE Group Inter-
face Module: As shown in Figure 5.13 in Chapter 5 &
Figure Serial Communication 2 in Appendix D, a complete
MR100 for Windows CE Group Interface Module consists
of these three components: (1) Programmed QTERM-A7
touch screen terminal (Nextron part number 9003-0062_1);
(2) Cable for QTERM-A7 (Nextron part number 9003-0063);
(3) 12Vdc power supply (Nextron part number 0507-0002).
