Programming a vibration channel
The default setting for the vibration measuring time (C) is 1 second. The time can be set to max.
15 seconds.
On the menu (D) you see the alarm limit A1 (max) corresponding to the selected ISO machine class
number. Changing the alarm limits menu removes the machine class information (see previous
page, A). The alarm level A2 (min) is default 0.5 mm/s.
System alarm (TLTA) and the two alarm limits A1 and A2 can be linked to any of the available relays
by setting the relay number 1 to max. 5. Each relay can be linked to more than one alarm cause.
The setting ” - ” means no link to a relay.
On the menu (E) you set the link to an analog output channel for the 4 - 20 mA signal by setting a
channel number from 1 to max. 4. The analog line can not, of course, be linked to more than one
measuring channel. When stepping with UP or DOWN, only free channel numbers are displayed.
On this menu, you also set the measuring range to max. 10, 20, 30, 40, or 50 mm/s RMS. The
analog current will be scaled accordingly, max. vibration value = 20 mA out.
Alarm delay is set in steps of 2 seconds by stepping to a number above 0 on menu (F). The maxi-
mum is 600 seconds or 10 minutes.
