SP.9 RTD Configuration (Setpoint Page 9)
(Security Level: 3)
The soft starter comes with an RTD card that provides 12
programmable RTDs which are individually programmable
for type. The available types are 100 ohm platinum, 100 ohm
nickel, 120 ohm nickel and 10 ohm copper. Each RTD can
be identified with a description name of up to 15 characters
(including spacing). Also, each individual RTD has it own alarm
and trip level.
SP9.1 Use NEMA Temp for RTD Value: When this setpoint
is enabled, the soft starter will use the NEMA design
insulation class to limit the maximum allowed range
of the alarm and trip level. The maximum allowed
temperature range is 240° C or (464°F).
SP9.2 # Of RTD’S Used for Stator: Up to six RTDs can be
assigned to monitor the stator of the motor.
SP9.3 RTD Voting: When this is enabled, the soft starter will not
post a trip until 2 RTD’s have exceeded the trip level.
This prevents nuisance RTD tripping.
SP9.4 All 12 RTDs are configured in the following manner. The
first column is the RTD type, the second column is the
RTD description, the third column is the alarm level,
and the fourth column is the trip level.
The first six RTDs have been pre-programmed with
a description name for the STATOR, with two RTDs
per phase. RTDs #1 & #2 have been named STATOR
PHASE A1 and A2 respectively. RTDs #3 & 4 are
named STATOR PHASE B1 and B2, RTDs #5 & 6
are named STATOR PHASE C1 and C2. If other
description names are required, press the right arrow
button from the RTD Type screen to go the RTD
description screen. If no alarm or trip level is required
these setpoints can be turned off.
