For a complete system, choose one of each of the following:
- Chassis
- Flame Detector
- Programmer Module
- Wiring Base
- Amplifier Module
WARNING: Installer must be trained and qualified. Follow the burner manufacturers in-
structions, if supplied. Otherwise, proceed as follows:
INSTALLATION OF CONTROL
Wiring Base
Mount the wiring base on the burner or on a panel. The location should be free from excessive vibra-
tion and within the specified ambient temperature rating. The base may be mounted in any angular
position.
All wiring should comply with applicable electrical codes, regulations and local ordinances. Use
moisture resistant wire suitable for at least 90 degrees C. Good electrical wiring practice should be
followed to ensure an adequate ground system. Refer to Fireye Service Note 100 separately and Gen-
eral Grounding Rules, later in this document, for recommended grounding methods
A good ground system should be provided to minimize the effects of AC quality problems. A prop-
erly designed ground system meeting all the safety requirements will ensure that any AC voltage
quality problems, such as spikes, surges and impulses have a low impedance path to ground. A low
impedance path to ground is required to ensure that large currents involved with any surge voltages
will follow the desired path in preferences to alternative paths, where extensive damage may occur to
equipment.
Refer to suggested Wiring Diagram on page 32.
WARNING: Controls require safety limits utilizing isolated mechanical contacts. Electronic
limit switches may cause erratic operation and should be avoided.
BEFORE INSTALLING THE CONTROL
CAUTION: Ensure that electric power is turned off. Refer to SN-100 for recommended
grounding techniques.
Be aware that power to some interlocks (operating controls, air flow switches, modulating cir-
cuits, etc.) may be derived from sources other than what is controlling the Flame-Monitor.
If either a ground or a short circuit is detected, it must be eliminated before the control is plugged
into the wiring base and power turned on.
Test the electrical field wiring for short circuits and grounds. The recommended method requires the
use of an ohmmeter set on its lowest resistance scale.
Note: When using ultra-violet or infrared scanning, be sure to remove any jumpers on the wiring
base which ground the S2 terminal.
1.
Touch the meter probes together and calibrate accurately to ensure a reliable test.
2.
Disconnect the neutral wire (L2) from the control system at the power source. Clip one meter
test lead to the grounded green terminal on the lower right side of the wiring base and with the
other probe touch each other terminal. At no time should the meters show continuity or read 0
ohms.
