Machine Guard MG4-REF11A

Machine Guard MG4-REF11A is a continuous monitoring unit. It measures vibration severity (VIB)
and the mechanical shocks (SPM) arising when the disc segments in a refiner touches each other.
It provides, for each channel:
• Status display (green - red light) and system fault (yellow light)
• Display of measured value with continuous updates
• Analog output current 4 - 20 mA with programmable range
• Relay action at two programmable alarm levels (red alarm)
When the unit is in its normal measuring mode, the green - red status light shows the status of the
channel with the worst condition. The yellow status light indicates system fault. The display shows
the measuring result on both channels.
On pressing SET, the cursor will be on channel 1 and the status light will correspond to the result
on channel 1. With SET one can step through all channels.
Pressing LEFT or RIGHT opens a window where you can see the instrument version, set measuring
unit and contrast, disable the TLT alarm and switch off the measuring function.
Pressing ENT starts the programming mode for the selected channel. This is password protected.
With the password set to ON, you can see the channel configurations but are unable to make
changes.
