Programming a vibration channel
To enter the programming mode for a channel, select the channel with the SET key (moves the
cursor at the beginning of line 1 to the next line), then press ENT. You get a sequence of program-
ming menus.
The cursor will jump to the next position which can be changed whenever you press the SET key. In
each programmable position, the keys UP and DOWN will alter the value. When a programmable
parameter consists of several positions, e.g. a three digit number, you go to the next position with
RIGHT, or to the previous position with LEFT.
The first line contains the channel name. This can be changed, one position at a time. The new
channel name is also shown on the following programming menus.
TLT (line 2 on menu A) means transducer line test and shows the transducer line quality. For a VIB
channel it can be OK (no fault), H = high (interrupted circuit) or L = low (short circuit).
Line 3 on menu (A) contains a parameter, the ISO machine class number. Setting one of the num-
bers 1 to 6 will automatically set the limit for “unacceptable” vibration as alarm level A1 (max) (red
alarm). The alarm level A2 (min) is the minimum alarm (red alarm).
Alarm will be triggered when
the level is above A1 (max) and below level A2 (min). The setting “ – “ means no machine class
and requires a manual entry of the alarm limits on a later menu. Changing the alarm limits on that
menu removes the machine class information on menu (A).
On menu (B) select the transducer sensitivity value (0.9–12.0 mV/m/s
2
). Enter the value from the
transducer’s calibration/data card.
