2.2 Removing the rec. chart from the take-up roll
(see figure 12)
2.3 Changing the chart speed
When the recorder is fitted with the option "Limit monitor and
binary inputs", two chart speeds are externally selectable. The
desired values for speed 1 and speed 2 are selected in parame-
terization mode (see parameterizing instructions 14083).
Speed 1 is active after the recorder is switched on.
Speed 2 becomes active by applying a voltage of 24 V DC
between terminals 901 (–) and 922 (+).
2.4 Standby function
When the recorder is fitted with the option "Limit monitor and
binary inputs", the recorder can be switched to standby. This
requires a voltage of 24 V DC to be applied between terminals
901 (–) and 912 (+).
In standby mode, the chart speed is switched off and is 1 mm/h
(depending on the parameterization). The measuring systems are
at the beginning of the scale. Processing of measured data and
limit monitoring are active. When a limit is violated, or when the
applied voltage is disconnected, the standby mode is inactivated.
The recorder starts to record.
Figure 11 Removing the recording chart
The recording table may be left in the unit when removing the
chart.
Recording table for chart rolls
1. Unfold the chart guide downwards.
2. Remove the take-up roll.
3. Eventually separate the chart at the tear-off edge.
Recording table for fanfold chart
1. Unfold the chart guide downwards.
2. Remove the recording chart.
3. Eventually separate the chart at a fold.
Note
Two folded layers of the chart must rest in the chart compart-
ment.
Figure 12 Removing the recording chart from the take-up roll
1. Turn the flange without drive pinion through 45° and remove it
from the take-up roll.
2. Grip the chart as shown in figure 12 and pull it off the axle.
3. Re-attach the right flange to the take-up roll and secure it by
turning it through 45°.
4. Insert the take-up roll into the recording table. The drive pinion
must be on the right side.
5. Close the chart guide.
