Description
The Series 1500 is a microprocessor based alarm
and/or shutdown system. It tells in alphanumeric
characters which protective device has signaled an
alarm or caused equipment shutdown. Basic config-
uration for each application is programmed at
Murphy and can be configured in the field.
Information is called up and adjustments are made
on a six-button keypad on the face of the unit.
The S1500 system consists of a monitor, a sensor
input terminal strip (rail mount type), a 36 inch
(914 mm) flat ribbon cable for connecting the ter-
minal strip to the monitor, and a power supply
which includes the control Inputs/Outputs and
intrinsically safe barrier with cable assembly.
Four SPDT relays are available for alarm and/or
shutdown functions. A built-in RS232 communica-
tion port allows interfacing with IBM
®
PC and com-
patible computer systems and micro-controllers.
The S1500 is powered from a 120 VAC or 12 or
24 VDC, Class I, Division 1 explosion-proof power
supply. The monitor is rated intrinsically safe.
Intrinsically Safe Barrier
Murphy’s LCDT-ISB intrinsically safe barrier for
hazardous applications, is designed for use with
two Normally Open sensors. This external barrier
accepts non-intrinsically safe, normally open inputs
and converts them to intrinsically safe outputs.
Applications
The Series 1500 can be configured to monitor
applications such as:
■
Generators
■
Air compressors
■
Process control
■
Gas compressors
■
Water treatment
■
Fire pumps
■
Burner systems
■
Sewage pumps
■
Natural gas refueling
Features
■
32 sensor inputs (N.O. and/or N.C.) for alarm
or shutdown.
■
Six-button keypad for easy operation and
adjustments.
■
RS232 output for interface with computers and
micro-controllers (modem required).
■
Engine Automatic.
■
Two Start-Run Timers.
■
Four Control Relay Outputs.
■
Pre/Postlube Time Delay.
■
Typical standard program or customized*.

Murphy provides various standard preprogrammed
configurations. If a customer sensor input configura-
tion is needed, Murphy will custom program your
unit at the time you order. Call Murphy for quote.
