Software module 911 - Backing pump speed
This module can be used with TIC compatible backing pumps with speed feedback.
Note:
Provided to support future backing pump enhancements.
General Description
Monitors Backing Pump speed (if pump has compatible speed feedback).
Output bytes (from Master)
None.
Input bytes (to Master)
No Alerts currently exist for these software modules so the 3rd and 4th bytes will always be zero.
Associated Parameter options
None.
4.8.16
Software module 912 - Backing pump power
This software module for use with 24Vdc backing pumps compatible with a TIC controller.
General Description
Monitors Backing Pump power (if pump is 24vdc powered from the TIC).
Output bytes (from Master)
None.
Input bytes (to Master)
No Alerts currently exist for these software modules so the 3rd and 4th bytes will always be zero.
Associated Parameter options
None.

Linking gauges and pumps
The TIC Profibus module can be used to link items. Further information about linking can be read in the TIC
instruction manual D397 22 880 Section 4.13. The information below provides details about linking using the TIC
Profibus module.
Controlled gauges (AIMs and AIGX) and Turbo pumps can be controlled over Profibus in Data exchange. Linking can
also be set up by parameterisation of the TIC such that the TIC will turn on/off linked items at the specified pressures,
voltages or speeds from a controlling item (master object).
However, the linked state will soon be overwritten by the Data Exchange value. To let the TIC linking be in complete
control, a value of '99' (Device 'leave alone') should be used in the Output data from the Profibus master.
