A Tank Control Module (TD) is needed for a station
that has a Secondary Tank (H) with level monitoring.
The Tank Control Module does the following:
• Provides the electrical power and the I/O
connections needed to operate two tank Radar
Level Sensors (M, T), agitator speeds, and transfer
pump logic
• Monitors and provides real time tank level
information to the Intelligent Paint Kitchen software
• Controls agitator motor speed
• Turns the Fill Pump Transfer Solenoid (P) on and
off to keep the Primary Tank (G) filled to the correct
level
Electrical power to the Tank Control Module comes
from the DC Power Supply with Barrier (S) located in
the non-hazardous location.
Within a paint kitchen, the Tank Control Module
is connected directly to the Pump Control Module
(PD) with a pair of fiber optic cables. All signals to
and from the Tank Control Module pass through
the Pump Control Module. A Tank Control Module
is needed in a system that has no Pump Control
Module. Connect the Tank Control Module to a fiber
optic converter in the Supervisor Box (A).
NOTE: NOTE: The Pump Control Module and Tank Control NOTE:
Module look identical to each other, but they are not
interchangeable. Each type of control module has its
own unique software installed.

A Radar Level Sensor (M, T) is used to monitor the
level of material inside the tank.
• 25D293 - Contains an Endress+Hauser™
FMP50™ wave-guided radar sensor with FM
approval.
• 25D294 - Contains an Endress+Hauser™
FMP50™ wave-guided radar sensor with ATEX
and IECEx approval.
For complete warnings, approvals, and operation
instructions, see the manufacturer's manual
(supplied).
A digital display allows the current level to be read
locally.
Suitable Radar Level Sensors may be obtained from
various manufacturers.
The Radar Level Sensor software communicates
tank level data to the Pump Control Module (PD) or
Tank Control Module (TD), which can be set to turn
on the Pneumatic Remote Transfer Fill Pump (N) to
refill the tank when needed.
