WARNING
If using a Rosemount IMPS 4000 or SPS 4001B, install it in a non-hazardous, explosive-free
environment.
2.3.5 Calibration handshake logic I/O
You can use the output signal to trigger an alarm or to provide a calibration handshake
signal to a Rosemount
™
IMPS 4000 or SPS 4001B.
1. If you are not using autocalibration, the transmitter provides a common bi-
directional logic contact for any of the equipment alarms listed in Table 2-8 . The
assignment of alarms that will actuate this contact is modified by one of seven
additional configuration settings (mode 1 through mode 7) listed in
Table 2-9 .
2. The logic contact is self powered, +5 Vdc with a 340 ohm series resistance. An
interposing relay is required if the logic contact will annunciate a higher voltage
device, such as a light or horn. An interposing relay may also be required for certain
DCS input cards. A Potter & Brumfield model R10S-E1Y1.OK 3.2 mA DC (or equal)
interposing relay will be mounted where the contact wires terminate in the control/
relay room.
Install cover ( Figure 2-14 ) and secure with captive washer, cover lock, and screw.
2.3.6 Install interconnecting cable
Note
If you did not purchase the interconnecting cable with the transmitter, consult the factory
for the proper wire type and gauge.
Procedure
1. Remove cover from the junction box. Connect the electronics end of the
interconnecting cable to the
FROM PROBE
side of the terminal block ( Figure 2-18 ).
WARNING
If using a Rosemount
™
IMPS 4000 or SPS 4001B, install it in a non-hazardous,
explosive-free environment.
