Timer
Set for continuous (hold) operation or set for countdown operation in 5-
minute increments from 5 minutes to 200 hours. Timer counts up or
down in 5-minute increments.
Alarms
Audible and visual alarms for adjustable tracking high/low RPM, inde-
pendent platform monitor (check belt), adjustable tracking high/low
temperature, independent over temperature, temperature sensor failure,
run termination and power failure.
Safeties
Over temperature alarm conditions shuts down heaters, independent
platform monitor alarm condition shuts down motor.
LCD Display
40-character LCD readout continuously displays speed in 1 RPM incre-
ments, temperature in 0.1°C increments, and time to 5-minute incre-
ments.
Microprocessor
Non-volatile memory retains all programming and automatically restarts
in the event of a power failure, controlled acceleration provides smooth
start up and stopping.
