SLATE™FUEL AIR RATIO MODULE 3
R8001C6001
Application
SLATE™ brings configurable safety and programmable logic
together into one single platform. The platform can easily be
customized for almost any requirement or application–offering
virtually limitless development opportunities with far less
complexity.
The R8001C6001 Fuel Air Ratio module uses the latest
technology to control up to 4 SLATE actuators and/or 2 Variable
Frequency Drives. The Fuel Air Ratio Control module controls the
relationship between fuel, airflow and flue gas recirculation on a
power burner.
Features
Within the SLATE system, the fuel air ratio module provides:
• Air-fuel ratio control for up to 4 actuators
• Drive 2 Variable Frequency Drives (VFDs)
• RS-485 Modbus communications to communicate to the
actuators and receive feedback
• SLATE actuator torque sizes:
– 50 in/lb (NEMA 1 and NEMA 4)
– 150 in/lb (NEMA 1 and NEMA 4)
– 300 in/lb (NEMA 4)
– 900 in/lb (NEMA 4)
• Up to 24 points
• Field configurable
• Automated actuator endpoint seeking process
• UL Recognized and NFPA acceptable
• Password protected
• Fault information
• Status of four actuator channels
• Unused VFD terminals (Analog Cells) available for general
purpose I/O configuration
• Flue Gas Recirculation (FGR)
• Trim
• Dual Fuel

432-00006—03
Safety Features
• Class C operating software system
• Fail-safe feedback
• Curve verification algorithms
• Password protected
• Built in self test
• No slope constraints that would limit the steepness of the
curve
• Component anti-swap protection
• Off curve checking algorithm

LED Array
There are three LEDs on the front of the Fuel Air Ratio module
that provide quick identification of the system status and any
problems that might occur. The status is broadcast to other
modules on the platform bus in case they are affected by the
inoperable modules. See Table 1 for descriptions.
LED Color Description
Power No light System does not have power
Green System has power
CPU Red No valid conguration
Green Running
Fault Red Fault
No light No fault
Table 1. LED Descriptions.
LED Displays
The SLATE system modules have three-character LED displays
used for indicating the module number of the SLATE system.
They also have three-position LED colors to indicate terminal
states as shown in Table 2.
Color Description
Green Terminal is ON or is Normal
Red Fault
No light Terminal is OFF or Not in use

Select and Reset Buttons
The SLATE system modules have Select and Reset buttons
located on the front of the module and beneath the segment
display. The Reset button is used to clear a lockout and reset the
module. The Select button is used to scroll through the segment
display information.
Installation
WARNING
Fire or Explosion Hazard
Can cause severe injury, death, or property damage.
Verification of safety requirements must be performed
each time a control is installed on a burner to prevent
possible hazardous burner operation.

Wiring
WARNING
Electrical Shock Hazard.
Can cause severe injury, death or equipment damage.
1. Disconnect the power supply before beginning installation to
prevent electrical shock and equipment damage. More than
one power supply disconnect can be involved.

IMPORTANT
1. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance
with these instructions, may cause interference for radio
communications. It has been tested and found to comply
with the limits of a Class A computing device of part 15
of FCC rules, which are designed to provide reasonable
protection against such interference when operated in a
commercial environment. Operation of this equipment in a
residential area may cause interference; in which case, the
user, at their own expense, may be required to take whatever
measures are required to correct this interference.
2. This digital apparatus does not exceed the Class A limits for
radio noise, set out in the Radio Interference Regulations of
the Canadian Department of Communications.
3. Cable shield must be terminated to ground at both ends. If
shielded cable is NOT used, use three-wire twisted cable.
WARNING
Fire or Explosion Hazard
Can cause severe injury, death, or property damage.
Disconnect the power supply from the main disconnect
before beginning installation to prevent electrical shock
and equipment damage. More than one disconnect can
be required.

Recommended Grounding Practices
Use an Earth ground or a signal ground as described below.
Earth ground (Base, Rectification Flame Amp
Module, other modules optional)
1. Use to provide a connection between the base and the
control panel of the equipment. Earth ground must be capable
of conducting enough current to blow the breaker in the event
of an internal short circuit.
2. Use wide straps or brackets to provide minimum length,
maximum surface area ground conductors. If a leadwire is
required, use 14 AWG copper wire.
3. Make sure that mechanically tightened joints along the ground
path are free of nonconductive coatings and protected against
corrosion on mating surfaces.
Signal ground
Note the 18V system ground is not electrically connected to earth
ground. Follow local codes and appliance recommendations to
determine if this should be connected to earth ground.
