Control Features
A compact Programmable Logic Controller (PLC) controls and monitors the transmissions functions. There is an electrical contactor for starting and stopping the hydraulic pump. Field devices include solenoids (2) to control the position of the disc with hydraulic positioning, pressure transmitters (2) to monitor fluid pressure, and temperature sensor (1). All operator functions are controlled from a control pad on the front of the PLC. The PLC is also designed to communicate with Pump Off Controllers. The communication between the two units has already been programmed into the Turbo Trac controller. Software is also available to run on a portable laptop to monitor and record values for conducting diagnostics.
The PLC continuously monitors the pressures and temperature of the IVT. Based upon user set points, the PLC will provide shutdown commands to the prime mover to prevent damage to the process if any user set limits are exceeded.
The PLC has analog input capabilities to receive speed actual and speed set point from customer speed controller.
PLC also has various network communication protocols to allow networking of the IVT with other equipment in the process.
Control Options
- Turbo Trac micro-processor for safety circuit monitoring and speed regulation – This is standard as a basic safety control circuit unless option 4 below is selected.
- Turbo Trac micro-processor with data logging – This is an enhancement to option 1 and provides data logging to an installed SD card port. SD cards supplied by user.
- Turbo Trac micro-processor with Telemetry for real-time monitoring – This is an enhancement to option 1 and provides Radio Frequency telemetry to transmit information to central monitoring/data collection system. Included in the feature is web based features for e-mail notification and web based monitoring.
- Can interface with customer automation to displace Turbo Trac processor - If the user has existing PLC’s available, Turbo Trac will provide programming logic to incorporate controls into user device and displace Turbo Trac PLC to accommodate process simplification.
Three options for speed regulation
- Manual Handle control – Lowest cost, lowest level of speed regulation, rate of change is dependent on operator
- Hydraulic control – Standard supply. Uses existing hydraulic system. Good speed control and resolution. Good speed rate of change. Can use 12/24 VDC or and AC line supply.
- Electronic control – High cost speed regulation. Very have speed resolution and high speed rate of change. Requires 220 VAC supply
Speed regulation from fixed up to 120 rpm/sec change rate.
Output speed resolution control; 1% on hydraulics to .1% for electronic control.
Safety monitoring provided for temperature, lubrication pressures interfaced with run permissive.
