The
D280 is a unique control designed to provide a precise bi-directional
(up and down) 0-10vdc speed pattern to provide the
smoothest possible controller response during acceleration and deceleration
of the elevator car. Unique to the D280 is the ability to control
both the rate and the SHAPE of the pattern allowing the adjuster
to compensate for the dynamics of the elevator system and provide
a very smooth car ride. Compatible with a wide variety of elevator
drives such as DC, ACVVVF or generator controls, the D280 accepts
dry contact closures and provides adjustments for up to six speeds,
two different acceleration and three (up to four via jumper) deceleration
rates. Direction of the pattern is selected via UP/DOWN direction
inputs. Other feature is an adjsutable "Dead-Zone-Tme Delay" which
allows the output signal to ramp to zero during the interval between
the drop out of the "Run" input and engagement of the mechanical
brake which eliminates rollback. Requires +/- 15VDC for the on-board
circuitry usually available at the terminal blocks of most elevator
drives. Included is a comprehensive step-by-step manual for smooth
and sucsessfull installation.
