GE VMIVME-4905 Parser converter
A grounding (earthing) connection is required. Connect minimum 12 gauge (3.31 mm2) ground wireto the Earthing Connection on the Oven Compartment and on the Master Controller.
WARNING – Bodily injury. The Neutral and Ground (earth) connections to the PGC5000
series Master Controller and B class oven must be at earth (0 volts) potential. Failure to
maintain earth (0 volts) potential at these connections points constitutes a serious safety
hazard.
2.6 Set up the Master Controller
The Master Controller (see Figure 2-2) must be installed according to all applicable codes. If it will be
in a hazardous area, the wiring method must conform to the applicable requirements. General Master
Controller connections include:
Power wiring (circuit breaker protection must be supplied by the customer); refer to the
installation wiring drawing provided in the Data Package for details.
Signal fiber between the Master Controller and the Oven(s).
Alarm contact outputs; refer to the installation drawing in the Data Package for details.
Neutral and Ground (earth) connections must be at earth (0 volts) potential.
WARNING – Bodily injury. Failure to maintain earth (0 volts) potential at Neutral and Ground
connection points constitutes a serious safety hazard. There could be damage to equipment.

Refer to the applicable drawings in your Data Package for specific interconnection wiring information.
2.6.1 Single board computer PCB
The Master Controller and the Oven with Controller contain a Single Board Computer (SBC). The SBC
has built in redundant Ethernet Network Interface Connections (NICs) located at the top center of the
SBC, labeled J6 and J8. Note that Ethernet 1 is to the right and Ethernet 2 is to the left.
The SBC has an SBC CAN Interface Card for each oven, labeled 1 through 4 from left to right. This
module communicates with the oven via fiber optic cables attached to the board by two connectors.
The fiber optic cables utilize two type ST connectors. The customer is required to install all fiber optic
connections.
NOTICE – Equipment damage. Sharp bends in a fiber optic cable can cause signal
attenuation or the optical fiber to break.
The ST connectors have a bayonet mount and a long cylindrical 2.5 mm ceramic or polymer ferrule to
hold the fiber. They are spring-loaded and keyed with slots and alignment nubs. Always “stab and
twist” to make sure the ST connectors seat properly.

IMPORTANT NOTE: If you have signal loss, remove and reconnect to see if this eliminates the
problem.
Optical fiber consists of a core, cladding, and a protective outer coating, which guides light along the
core by total internal reflection.
2.6.2 Purge air alarm
The Purge Air Alarm must be monitored if the analyzer is equipped with pressurization protection.
Connect the Purge Air Alarm wiring to connector J19, pins 1 to 3, on the Single Board Computer. Refer
to the Data Package for more detailed information.
IMPORTANT NOTE: The alarm contact is set in normally-open configuration for failsafe operation.
The Purge Alarm input must be configured to indicate a non-alarm condition when the contact is
closed. The Purge Air Alarm is a dry contact rated for a maximum of 5 W at 30 Vdc or 0.25 A
maximum.
The Common Malfunction alarm connections use J19 pins 4 to 6. Refer to the Data Package for more
detailed information.
2.7 Set up the ovens
Each oven must be installed according to all applicable codes. If it will be in a hazardous area, the
wiring method must conform to the applicable requirements. General connections to the oven include:
Power wiring (circuit breaker protection must be supplied by the customer); refer to the
installation wiring drawing provided in the Data Package for details.
Signal fiber between the Master Controller and the Oven(s)
Alarm contact outputs; refer to the installation drawing in the Data Package for details.
Neutral and Ground (earth) connections must be at earth (0 volts) potential.
WARNING – Bodily injury. Electrical hazard from line voltage. Failure to maintain earth (0
volts) potential at Neutral and Ground connection points constitutes a serious safety hazard.
There could be damage to equipment and bodily injury.
Refer to the applicable drawings in your Data Package for specific interconnection wiring information.
Connect the oven purge alarm to connector J10 pins 1 (NC), 2 (C), and 3 (NO) on the DTC Digital
PCB. Refer to the Data Package for more detailed information.
The General Purpose alarm connections use pins 5 and 6 of the mating connector and connect to J10
on the DTC Digital PCB. Refer to the Data Package for more detailed information.
The Oven with Integrated Controller contains an SBC (see section 2.6.1 for additional information).
The Purge Air Alarm function on the SBC is not used in the Oven with Integrated Controller.
3 Startup
3.1 User interfaces
The application configured at the factory establishes the operational baseline and expected results as
requested by the customer. The analyzer can be controlled at either the Local User Interface (LUI) if
provided, or the Remote User Interface (RUI). While these interfaces can work simultaneously on an
analyzer, they work independently of each other. The last function to save data is the one effective on
the analyzer.
3.2 Master controller controls and indicators
Normal operation of the analyzer is controlled from the Master Controller front panel (see Figure 3-1)
which has the touchscreen display and keypad.
