The MUTE indicator will extinguish to advise that the audible alarm is active.
The alarm will not sound while the shaker is accelerating immediately following turning on the power.
5.6 Total running time
The control modules of the Innova shakers keep track of the time the shaker has been on, tracking the
hours of usage.
To display the accumulated running time:
1. Select HRS using the SELECT key.
2. Simultaneously press the and keys.
The SET and MAINT indicators will flash and the accumulated running time will be displayed in
hundreds of hours (i.e., “02” equals 200 hours; “102” equals 10,200 hours). This display will continue
for 10 seconds and then default to the previous mode readout.
5.7 Temperature/monitor option
This option consists of an internal electrical interface, an RTD temperature probe and an analog output for
chart recorder or data aquisition system. When this option is installed, either the ambient temperature or
the temperature of any vessel on the shaker platform can be measured with the probe:
1. Remove the probe from its holder and insert it into the vessel to be monitored.
2. Use the SELECT key to indicate °C.
Since the temperature/monitor option does not provide temperature control, any attempt to enter a
temperature setpoint results in the display of
Err on the control panel.
The shaker may be stopped or started by pressing the START/STOP key. When starting, the
unit will automatically return to the last function and speed setting.
The audible alarm will sound until the speed is within 5
rpm of the setpoint.
After 10,000 hours of operation, the MAINT indicator will light. Preventive maintenance is
recommended at this point. The Eppendorf Service Technician will deactivate the light when
the technician performs the required maintenance.
The °C indicator will only function when the temperature/monitor option is installed.
