2018KCL(ip) SERIES SIGNAL MONITOR
OPERATIONS MANUAL
Section 1
BASIC FUNCTIONS
1.1 MODEL DESCRIPTION
The model 2018KCL unit is an eighteen channel version of the 2010ECL model, and is
compatible with the requirements of both the 170 Controller Unit and the 2070 Advanced
Traffic Controller. The need for diode based program cards and on-board DIP switches for
configuration has been replaced with the interchangeable Datakey device. The default
configuration meets the requirements of the industry 2010 specification. Where not
specified otherwise, the information in this manual will apply to all models.
The 2018KCL is completely compatible with cabinets wired for conventional 16 channel
monitor operation. All monitoring functions related to channels 17 and 18 may be disabled if
necessary.
The model 2018KCL has a three color LED full intersection display and an EIA-232 serial
port that gives the unit the capability to communicate with Controller Unit or PC based
operational software for status and fault event data. The model 2018KCL also provides an
enhanced event logging capability for full time stamped event reporting to the Controller
Unit or PC based operational software. The model 2018KCLip provides an Ethernet port in
place of the standard EIA-232 serial port.
1.2 BASIC FUNCTIONS
The 2018KCL Signal Monitor is a device used in a traffic controller assembly to monitor
traffic signals at an intersection for conflicting proceed indications caused by malfunctions
of the controller, load switches, field wiring and loads, or miss-wiring of the cabinet. The
2018KCL also provides error sensing of the cabinet 24VDC supply and monitors the
controller Watchdog output. The 2018KCL is directly interchangeable with a standard
model 210 Signal Monitor and complies with all applicable specifications outlined in
Chapter 4 (Model 210 Monitor Specifications) of the Caltrans Traffic Signal Control
Equipment Specifications (January 1989).
When triggered by the detection of a fault condition which exists longer than the minimum
period, the 2018KCL will enter the fault mode transferring the Output relay contacts to the
fault position and enabling the Stop-Time output to the controller. The cabinet assembly
should be wired such that the transfer of the Output relay contacts to the fault position will
cause an automatic switching of the field signal outputs from normal operation to flashing
operation. The 2018KCL will then display the appropriate fault indications and will remain in
this fault mode until a reset command is issued. The loss of AC Line power will not reset
the fault mode (except Diagnostic Fail). In the event of AC Line power loss the 2018KCL
will retain the status of all fault and channel indicators and will display the correct fault and
channel status upon restoration of AC Line power.
1.2.1 DATAKEY PARAMETER PROGRAMMING
The 2018KCL is configured using a removable nonvolatile memory device called a
tm
Datakey
(Datakey is a trademark of Datakey Electronics, Inc.). The Datakey replaces the
mechanical jumpers, DIP switches, and diode based program card used in conventional
signal monitors and provides an interchangeable and electronic method of programming
the unit. The Datakey contains a nonvolatile prom device that is read by the 2018KCL. The
Datakey itself is programmed by a separate programming tool using a Personal Computer
®
program such as the Eberle Design MonitorKey
product. See the Eberle Design
MonitorKey Operations Manual for further details.
