To set a new Hold temperature, press
the Temp button twice. The screen at
right appears. The Hold temperature
flashes.
Using the up and down arrows, program a new Hold temperature. Press
the Temp button or press nothing for about 15 seconds to save the new
setting and return to the Operating Screen.
1. Press the button beneath the speed setpoint. The speed value will begin
to flash.
2. Press the up or down arrows to set the new speed in 1 RPM
increments. Hold either arrow button to scroll. However, if the up or
down arrow buttons are held for about 2 seconds, the display will scroll
in that direction.
3. Press the speed button again to return to the Operating Screen.
Speed can be set over a range of 25 to 400 RPM.
The Stackable Shaker manages operating time in two ways:
Hold - When time is set to Hold, the value shown in the 'Actual' display
represents total operating time and may be reset at the operator's con-
venience. The shaker will continue to count upwards even if the shaker
door has been repeatedly opened and closed, or turned off and on with
the power switch. The time however, will reset to 00:00 when the STOP
button is pressed, then the unit restarted by pressing the START button.
Countdown - When the Hold setpoint is changed to Countdown, enter-
ing a time value in hours and minutes programs the platformto operate
for that period of time and automatically stop platform motion. The dis-
play will show the programmed time in the Setpoint segment and the
operating time remaining in the 'Actual' display, as the microprocessor
counts down to zero. The countdown time can be set over a range of 5
minutes to 200 hours in 5 minute increments.
An additional feature on Model SHKE8000-7 & SHKE8000-8CE is
Hold temperature. The refrigerated shaker can be programmed to oper-
ate at one temperature, then hold the cabinet at another temperature
when the countdown reaches zero. The platform will stop, but the fans
and the temperature control systems continue to operate.
