Measurement
signal
errors
are displayed at the top of
the display instead of the
measurements and statis-
tics. The message «Signal
failure» appears on the LCD
screen with 2 values (Fig.
65) A = X.X Volt and
dt = X.X ms
Fig.65
During the next correctly executed measurement or
when the device problem has been rectified, the values
and current statistics appear again.
10.3 Description of the measurement
signal errors
With the impact devices type P, PG and U with error
A = X.XX V
If the A-value is
below 3.30 V.
a
Clean the impact bodies and guide tube.
Refer to section 11 «Maintenance»
If the A-value is
higher
than
4.00 V.
a
Repeat the measurement with a slower loading
movement (section 10.1).
With the impact devices type P, PG and U with error
dt = X.XX ms
If the dt-value is
lower
than
0.40 ms
a
The support ring is worn; i.e. the impact body is in
an incorrect position at the time of measurement.
Replace the support ring.
On impact device type P with error dt = X.XX ms
If the dt-value is
higher
than
1.25 ms
a
The support ring is not correctly positioned.
Fit the support ring correctly on the end stop.
On impact device type PG with error dt = X.XX ms
If the dt-value is higher than 1.40 ms
a
