Diaphragm Dosing Pump Encore

9. Start-up
CAUTION!
The personal protective equipment specified by the applicable accident prevention regulations must be worn whenever working on the dosing pump/system.
Protective clothing
1.
All the work described in "Installation" (section 7) must be carried out before starting the dosing pump. The safety instructions (section 1) must also be
observed.
2.
Fill the dosing pump with the oil supplied. For oil grade and quantity, see paragraph 11.1.

3.
The Encore
ME dosing pump is switched on by a control to be installed externally. The Encore
control types are explained in section 8, Encore
4.
The manual capacity adjustment should be set to maximum stroke for better priming. During the initial priming, there should be no back pressure. For this
purpose, we recommend installing a relief valve on the discharge side of the dosing pump.
5.
If a priming aid has been installed, this must be filled with chemical first. If the dosing pump does not prime, switch off the dosing pump, unscrew the
discharge valve and fill the dosing head with fluid. If non-hazardous, the medium itself can be used; otherwise use a neutral medium that will not disturb the
process. (In many cases, water can be used.)
WARNING!
Chemical may spray out. This may lead to chemical or other burns. Ensure that the discharge line is depressurized before disconnecting.
Then, mount the discharge valve again, switch on the dosing pump and start priming. (A priming aid is recommended. See installation examples.)
6.
If there is a vent valve integrated in the dosing head or installed as a separate fitting, open it while the dosing pump is operating until fluid comes out. Then
close it again. In the case of outgassing media, allow the fluid to flow off continuously (about 1 drop per 1 - 3 strokes). The escaping fluid flows through a
hose back into the tank.
7.
When correct operation has been established, set the desired delivery rate using the adjusting knob (see section 8.1) or the remote control adjustment. For
an initial approximation, refer to the performance curves (section 5).
NOTICE!
Depending on the installation and the chemicals used, these values may differ and must be checked under operating conditions.
8.
The manufacturer of the dosing equipment is not responsible for damage due to excessive or insufficient flow rates at the dosing pump or incorrect or faulty
installation of peripheral fittings.
9.1 Start-up of Encore
Switch on the main drive motor of the dosing pump. An electrical interlocking system then allows ATE drive adjustment. To check the direction of rotation, send
short control pulses to the ATE servomotor. If the direction of rotation is wrong, adjust its direction as described in the ATE servomotor operating instructions. To
check the limit stop of the integrated limit switches, the ATE servomotor must be moved to the end position. The factory-set angle of rotation is 270°. If required,
the maximum delivery rate can be changed by limiting the angle of rotation. To do this, the trigger cams of the limit switches are moved.
