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.
