SLATE™LIMIT CONTROL MODULE 3
R8001L8001
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 R8001L8001 SLATE Limit Control Module is part of the
SLATE Combustions System. The SLATE Limit Control Module
provides the ability to bring in any type of analog signal and
create limits on either pressure or temperature without needing a
UDC Controller.
Features
• 12 limit blocks with each block monitoring any sensor or pair
of sensors
• One limit module for multiple burner controls
• 4 sensors available for Limit Block use (2 sets of redundant
safety inputs)
• Unused Analog Cells available for general purpose I/O
configuration
• Redundant limit relay output

R8001L8001
LED Array
There are four LEDs on the front of the Limit Control Module
that provides 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.
The LEDs on the module are for the sensors, the inputs and
outputs, and for the Reference V.
Terminals 18 and 19 are the limit contacts.
Terminals 20 and 22 are reference voltage terminals to indicate to
the Limit Module what reference voltage it’s operating at.

Table 1. LED Descriptions.
LED Display
The SLATE system modules have a seven-segment, three-
position LED display used for indicating the module number of
the SLATE system. The LED colors indicate the terminal state as
shown in Table 2.

Select and Reset Buttons
The SLATE system modules have a 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.
When Installing This Product

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 Interfeence Regulations of
the Canadian Department of Communications.
3. For combination gas-oil burner applications, a double pole,
double throw (dpdt) fuel select switch is required.
4. Cable shield must be terminated to ground at both ends. If
shielded cable is NOT used, use three-wire twisted cable.
Wiring
WARNING
Electrical Shock Hazard.
Can cause severe injury, death, or equipment
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.
