Conļ¬gurable Safety Modules
The safety modules in a SLATE control are:
SLATE Burner Control Module
R8001B2001/U
The SLATE Burner Control provides ļ¬ame safeguard controls
for a variety of applications within the SLATE system. It can be
conļ¬gured as a primary or programmer, semi-automatic, or fully
automatic. The Burner Control Module provides 24 VDC to 24
VAC to 240 VAC ļ¬ame safeguard, valve proving, parameters, and
behaviors that emulate the 7800 and Sola series ļ¬ame safeguard,
and dual fuel capability.
SLATE Flame Ampliļ¬er Modules
ā¢ R8001V1031/U Rectiļ¬cation with Dynamic Ampli-Check
ā¢ R8001F1041/U Infrared with Dynamic Ampli-Check
ā¢ R8001S1071/U Ultra Violet with Dynamic Ampli-Check
ā¢ R8001S1051/U Ultra Violet with Shutter- Check
ā¢ R8001F1091/U Ultra Violet/Visible Light with Ampli-Check
The Flame Sensor modules for a burner control belong to and are
operated by the parent safety module to implement some of its
safety-related inputs and outputs. These Flame Amp modules are
conļ¬gured as part of the parentās safety modules conļ¬guration.
Flame amp modules can be mounted on the DIN rail or can be
mounted remotely, such as to put a ļ¬ame module close to its ļ¬ame
sensor.
SLATE Fuel Air Ratio Control R8001C6001
and Actuators
(R8001M1050- 50 in/lb NEMAī1, R8001M1150- 150 in/lb
NEMAī1, R8001M4050- 50 in/lb NEMAī4, and R8001M4150
NEMAī4 Durastep actuators in 300 in/lb and 900 in/lb may also be
used.)
The SLATE Fuel Air Ratio Control Module controls the relationship
between fuel, airļ¬ow, and ļ¬ue gas recirculation on a power burner.
It provides control for up to 4 SLATE actuators and/or 2 Variable
Frequency Drives (VFD).
SLATE Limit Module R8001L8001/U
The SLATE Limit Control Module provides the ability to utilize
any type of analog signal and create safety limits on pressure or
temperature or both.
SLATE safety modules cannot be programmed; only the SLATE
Base provides this feature. The basic behavior of each safety
module is ļ¬xed but can be adapted to various purposes by
changing conļ¬guration parameters. The SLATE Burner Control
will have 70 parameters to tune and select behaviors. Examples of
these parameters include:
ā¢ Timings such as prepurge, ignition, and postpurge times.
ā¢ The type of ignition such as pilot or direct.
ā¢ The response to ļ¬ame failure such as lockout, recycle, or recycle
with a delay.
The inputs and outputs on a safety module are available to the
control parameters and status registers that are available to the
control program. Each of these also has a dedicated purpose. A
few examples, for a burner control:
ā¢ Parameter: the call for heat request (a non-safety signal which
typically would come from the control program)
ā¢ Status: the current burner state (e.g. Standby, Prepurge, Ignition,
Firing)
ā¢ Status: the elapsed time of the current state
Programmable Logic
A SLATE system also provides conļ¬gurable I/O modules that
provide inputs and outputs for use by the control program. Those
modules are:
SLATE Analog Module R8001U3001/U
The SLATE Analog Module provides a variety of different
combinations of analog input and output types; 0-10 VDC inputs
or outputs, 4-20 mA inputs or outputs, Thermocouples type J and
K, RTD, 3 wire NTC, Pulse Width Modulation, and Tachometer.
SLATE Digital Module R8001D4001/U
The SLATE Digital module provides 14 opto inputs or 6 relay
outputs.
SLATE Annunciator Module R8001N7001/U
The SLATE Annunciator module is designed to monitor the status
of a series string of limit, control, and interlock contacts for a
commercial or industrial burner. The Annunciator Module acts as
a system monitor and enhances fault and status messages of the
SLATE Burner Control Module.
A SLATE control program resides and is executed with the SLATE
Base Module. To create a control program the user utilizes a
āwire sheetā (part of the Honeywell SLATE tool) that resides on
a computer. The programming is performed by dragging-and-
dropping function blocks onto an editing screen, dragging lines
between the blocks to interconnect them, and opening a blockās
properties to setup its behavior.
When a wire sheet input block is used, the user can attach it
either to the data from an input terminal of any SLATE module, or
to a source of data from internal logic such as the burner status
information provided by a burner control.
When a wire sheet output block is used, the user can attach it
either to control an output terminal of a SLATE I/O module, or to
send data to the internal logic of another module such as the call
for heat request for a burner control.
More information on programming using the Honeywell SLATE Tool
is located in Chapter 2.
