4. Safety instructions
The following safety instructions refer to the ATE
servomotor. The instructions contained in the
enclosed operating instructions for the metering
pump also apply for the extended installation.
⇒ When working on the metering equipment,
observe the local safety rules.
⇒ Before working on the metering pump and the
ATE servomotor, disconnect the main power supply
and protect it against reconnection.
⇒ Adjustment works in the interior of the ATE drive
must be carried out carefully. Connections and
internal limit switches might be "alive".
⇒ Additional limit switches might be "alive" even
with the auxiliary voltage switched off.
⇒ After installation works at the ATE servomotor
or before startup remount the cover.

6. Start-up
Switch on the main drive motor of the metering
pump. With an electrical interlocking system, only
then can the ATE drive be adjusted.
To check the direction of rotation send short control
pulses to the ATE servomotor.
If the direction of rotation is wrong, the supply lines
(terminals 2 and 3 in the case of direct controls) are
reversed.
The ATE servomotor must be moved to the final
positions in order to check the limit stop mechanism
of the integrated limit switches. When leaving the
factory, the angle of rotation is 270°. If required, the
angle of rotation and thus the maximum flow rate
can be restricted. To achieve this, the upper trigger
cam is shifted by the required value.
