WARNING: Failure to properly calculate power supply DC output voltage
may result in inaccurate transmitter readings, possibly leading to safety
system performance degradation during design basis events. To avoid
equipment inaccuracy hazards, follow the examples and tables provided
in this section for determining the proper power supply DC output voltage.
Field wiring connections for the transmitter are presented in Figure 3.2. If the
transmitter is equipped with an EGS Quick Disconnect connector assembly,
make sure the two halves of the connector are secured with the bayonet ring.
See Operation of the EGS Quick Disconnect Connector Assembly,
page 22
, for
details.
It is important that the total loop resistance be less than the maximum cal-
culated resistance value and greater than or equal to the minimum resistance
value for proper operation under post-accident conditions. See Figure 3.3,
page 14
, for reference.
