TIMER (Shaker)
• Programmable shaking periods from 0.1 hour to 99.9 hours by a digital timer that shuts
off at the end of period and energizes status light.
• Timer counts down and digital display indicates remaining time. Can be deactivated for
continuous operation.
•
Additionally, unit will display total accumulated running time for service information.
AMBIENT OPERATING ENVIRONMENT
0
°
- 40
°
C, 90% humidity, non-condensing
SELF-DIAGNOSTIC STATUS
Warning signal (audible and visible) indicates when shaking speed deviates more than 5
RPM or the temperature deviates more than 1.0°C from setpoint and when timer operation
has expired. The audible alarm can be deactivated/activated by the operator.
REMOTE MONITORING
• Chart recorder outputs for speed and temperature (0-5V).
•
1V per 100 RPM; 1V per 20
°
C, accuracy
±
25mV.
