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:

■ Air compressors ■ Gas compressors ■ Fire pumps

■ Sewage pumps

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.
