The TTD is a fully configurable fault annunciator and shut-down control system designed to protect engines, compressors and associated equipment.
This easy-to-operate panel features a simple interface. One display head is common to all configurations which requires fewer spare parts. The optional tachometer may use CD ignition or MPU input. The panel offers optional pre-lube or post-lube functionality as well as optional no-flow detection. It can monitor 48 user-configurable sensors.
