Power and Control Cable
The S1400 module is connected to the power supply via the 9-conductor
shielded cable. The cable is factory-sealed on the power supply end, and
has a D-sub miniature connector on the monitor end. Outputs from the
module are transmitted to control relay drivers in the power supply via
four conductors of the 9–conductor shielded cable.
System Power Backup Battery
The backup power is provided by a 12 VDC, 600 MAh rechargeable Ni-
cad battery pack. A temperature compensated, constant current battery
charger maintains full charge on the battery pack when primary power is
on. If the battery is fully discharged when primary power is turned on, it
will take approximately 24 hours to bring batteries up to full charge. At
full charge the battery pack will maintain operation of the S1400 system
for approximately 5 hours after primary power failure. The battery out-
put is regulated to 6 VDC for the monitor supply voltage.
Sensor Inputs
The sensor inputs are divided into three major groups identified as class
“A”, class “B”, or class “C”.
Class “A” inputs are operative (armed) all the time.
Class “B” inputs are enabled after the preset Start-Run time period.
Class “C” inputs are armed only after the fault has been cleared
for (2) seconds. (Example: Process Variables).
Opto-isolated Input
The Opto-isolated input is a special input in the explosion-proof power
supply which can be preprogrammed as:
1. Remote Reset Input (standard programs): Resets Start-Run timer and
enables the Class “B” lockouts.
2. Explosion-proof Shutdown (optional): for Normally Open or for
Normally Closed systems.
Permissive Function
This function was designed to monitor prelube pressure input.
Terminal 32 of the sensor terminal block is reserved for a permissive pre-
lube input. The pressure signal can be obtained from a pressure switch
with normally open or normally closed contacts that indicates whether or
not sufficient oil pressure has been reached during prelubing. If permissive
pressure has not been reached, the system will not allow start-up.
Intrinsically Safe Barrier
The power supply circuit is isolated from the S1400 module by the
intrinsically safe barrier located on the printed circuit board (power sup-
ply enclosure), between the power supply output and the
power and
control cable terminal block.
The intrinsically safe barrier consists of seven (7) separate barriers. The
power output to the module is isolated by a Fuse Barrier (FB barrier)
mounted inside a sub-module attached to the power supply circuit board.
The four (4) control outputs from the S1400 module are isolated by
zener diode shunt barriers.
Remote Reset Function in terminal block
The S1400 can be configured for Remote Reset through sensor input ter-
minal #32 (must connect to dry contact mechanical switches, or an
approved explosion-proof barrier must be used).
