5.7 Acknowledging the MAINT Indicator
After the shaker has been operating for 10,000 hours accumulated running time
(initially, or since the previous maintenance check), the MAINT indicator light on the
control panel will light. Only an NBS service engineer can turn it off.
The MAINT light indicates that it is time for a routine maintenance check. A regular
schedule of routine maintenance is an excellent way to keep your valuable equipment
performing optimally for years of reliable service.
5.8 Recorder Adaptation
To record speed and temperature a recorder (not supplied) can be used. It should have
the following capabilities:
•
To record both speed and temperature, two channels are required. Each
channel should have signal conditioning which accepts 0-5 volt DC input. The
pin-out diagram and scale below identify the application.
•
A mating connector is required on the recorder cable (not supplied). This is a
9-pin male D subminiature connector, AMP Amplimite HDP-20 series or
equivalent.
