Description
The S1400 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 plug-
ging in a new preprogrammed microchip. A digital output version
(S1400-SP) interfaces with micro-controllers (7 bit straight binary code).
The basic system consists of (1) the module, (2) terminal block assembly
(32 position rail mount), (3) a 36 inch (914 mm) flat ribbon cable for con-
nection of the terminal block to the monitor, and (4) a power supply
which includes the control Inputs/Outputs and an intrinsically safe barrier
with cable assembly.
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.
Module
The S1400 module is the brain of the annunciator system. It contains a
microcomputer, a 32 point multiplexer, a dot matrix alphanumeric dis-
play and a 6-button membrane keypad for operator access to field
adjustable functions. (See figure, p-2.)
Display
The S1400 module displays each mode of operation. The display is a dot
matrix alphanumeric 32-character display. By observing the monitor the
operator can determine the operating status of the control system.
Power Supply
An explosion-proof enclosure designed for Class I, Division 1, Group D
hazardous locations (CSA approved.) contains the supply voltage condi-
tioning circuits, battery charger, module power supply, backup batteries
and the intrinsically safe barriers for isolation between the power supply
and the low energy module circuits. The power supply accepts 120 VAC,
50-60 Hz and/or 12-24 VDC input power. 24 VDC power can be used as
primary power or as a backup source of power when 120 VAC is used.
120 VAC power is connected between terminals #1 and #2 of the 18 posi-
tion power input and output terminal block. 24 VDC is connected between
terminal #3 and #4, with terminal #3 positive with respect to terminal #4.
Control Relays
The power supply has four control relays to provide form “C” SPDT
outputs. The output relay functions for Four Stage Electric Motor Driven
applications are: lube control, drive motor, cooler motor, and alarm.
The output relay functions for Four Stage Engine Driven applications
are: lube control, ignition ground, fuel valve control, and alarm. Relay
functions for custom programs will depend upon specific application.
Four light emitting diodes (LED's) located adjacent to the relays, turn
ON to indicate when the relays are energized.
System Input Terminal Block
Sensor input terminal block consists of a 64-position, 32 pair input rail-
mount terminal block for interface of panel or field-mounted end
devices. End devices must be mechanical switches (non energy storing
devices). The terminal block can be used for Normally Open sensors
(one wire), and/or Normally Closed sensors (two wires). Factory
installed jumpers are supplied for each sensor input.
Ribbon Cable
A 36 in. (914 mm) flat ribbon cable is required for connection of the
S1400 module and the sensor input terminal block. The cable is supplied
with two D-sub 37 PIN connectors at each end of the cable.
