Description

The Series 1400 is a microprocessor based fault annunciator. It tells in alphanumeric characters which protective device has signaled an alarm or caused equipment shutdown. Basic programming for each application is completed at Murphy and can be changed in the field by simply plugging in a new preprogrammed microchip. Information is called up and adjustments are made on a six-but- ton keypad on the face of the unit.

Four SPDT relays are available for alarm and/or shutdown functions. A digital output version (S1400-SP) port interfaces with micro-controllers (7 bit straight binary code).

The S1400 and S1400-SP are powered from a 120 VAC or 12/24 VDC Class I, Division 1 explosion-proof power supply. The monitor is rated intrinsically safe.

Applications

Although designed primarily as an intrinsically safe annunciator for gas compressors, the Series 1400 can be programmed to monitor most engine or motor driven process applications, such as:

■ Air compressors	■ Process control
■ Gas compressors	■ Water treatment
■ Fire pumps	■ Burner systems
■ Sewage pumps	■ Natural gas refueling
■ Generators

Features

■32 sensor inputs (N.O. and/or N.C.) for alarm or shutdown

■Six-button keypad for easy operation and adjustments

■Digital output for interface with micro-con- trollers (optional)†

■Adapter for CD ignition interface with opto- isolator input (optional)†

■Relay board expansion, provides 7 additional control relay outputs or binary representa- tion of alarm/shutdown terminal number (specify)†

■Start-run timer

■Four control relay outputs

■Pre/Post lube time delay

■Typical standard program or customized*

†These options are NOT approved by CSA.

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

Specifications

Power Consumption: 120 VAC (8 watts), 24 VDC (7.2 watts) or 12 VDC (2.5 watts).

Sensor Inputs: For up to 32 N.O. and/or N.C. inputs such as Murphy SWICHGAGE® instru- ments. Each input is factory programmed as a class A, B or C shutdown, alarm, or control function (specify).
