Terminal Connections (
continued
)
The following General Monitors Modules
provide power connections for the Model
S216A, but need a customer supplied DC
source:
l
DT210 Readout/Relay Display Module
without Power Supply & Relay Module
l
TA202A Trip Amplifier Module without a
PS002
Since the Model S216A is designed to operate
continuously, a power switch is not included,
in order to prevent accidental system shut-
down.
NOTE: Power must remain disconnected
until all other wiring connections have
been made.
The maximum distance between the Model
S216A and the power supply is 4500 feet
(1372 meters). See the Appendix (section
5.1.3) for cable length specifications. The
cable run should be as short as possible. To
c24VDC to the Model S216A,
connect the red wire to TB1, position 5 (CE
Mark units - TB4, position 2), labeled
+24VDC. Connect the black wire to TB1,
position 4 (CE Mark units - TB4, position 3),
labeled COM (figure 14).
3.5 Ap ply ing Power
Before applying power to the system for
the first time, all wiring connections should
be checked for correctness and the housing
cover replaced.
At the initial application of power, or after
a fault condition has been corrected, the
unit will indicate “
SU ” (Start-Up) before
entering the normal mode of operation.
General Monitors recommends that the
Model S216A be calibrated within the first
hour of operation after the initial
application of power and that a second
calibration be performed 24 hours after this
initial calibration. These two calibration
sequences should be performed with new
units and units that have been off of power
for more than a week. See Calibration
Mode, section 4.3 for more details.
