Surges/transients
The transmitter will withstand electrical transients of the energy level usually
encountered in static discharges or induced switching transients. However,
high-energy transients, such as those induced in wiring from nearby
lightning strikes, can damage the transmitter.
Optional transient protection terminal block
The transient protection terminal block can be ordered as an installed option
(option code T1 in the transmitter model number) or as a spare part to
retrofit existing Rosemount 4088 MultiVariable Transmitters in the field. For
a complete listing of spare part numbers for transient protection terminal
blocks, refer to the Spare parts list section in the Rosemount 4088
MultiVariable Transmitter Reference Manual. A lightning bolt symbol on a
terminal block identifies it as having transient protection.
Note
Grounding the transmitter case using the threaded conduit connection may
not provide a sufficient ground. The transient protection terminal block
(option code T1) will not provide transient protection unless the transmitter
case is properly grounded. See Transmitter case to ground the transmitter
18 Rosemount 4088A MultiVariable Transmitter Quick Start Guide
April 2019 Quick Start Guide
case. Do not run transient protection ground wire with signal wiring; the
ground wire may carry excessive current if a lightning strike occurs.
5.2 Install optional process temperature input (Pt 100 RTD Sensor)
Note
To meet ATEX/IECEx Flameproof certification, only ATEX/IECEx Flameproof
cables (temperature input code C30, C32, C33, or C34) may be used.
Procedure
1. Mount the Pt 100 RTD Sensor in the appropriate location.
Note
Use shielded 4- or 3-wire cable for the process temperature
connection.
2. Connect the RTD cable to the transmitter by inserting the cable wires
through the unused housing conduit and connect to the screws on
the transmitter terminal block. An appropriate cable gland should be
used to seal the conduit opening around the cable.
Note
If power is already connected to the Rosemount 4088, power should
be removed prior to connecting the RTD wires. This will allow the
Rosemount 4088 to detect the RTD type at startup. Once the RTD is
installed, reconnect power.
3. Connect the RTD cable shield wire to the ground lug in the housing.
