As an additional piece of safety equipment, laboratory shakers from IKA offer device-internal
monitoring with labworld VRIW ® or from the attached computer. If the control software or computer
fails (crash, loss of power, etc.), this system is able to turn off the shaker or to switch it over to a
safe speed range. The shaker’s Parameters dialog box is used to activate the watchdog, to set
the time window and to set actions to be initiated in the event of a fault.
The Time-out time of the watchdog must be selected so that is greater than the current sampling
rate of the measurement by a factor of at least 5.
The features for safety monitoring are not available until after the control path for the target speed
has been activated.
