Figure 3-2 DJ-100 Jet Operation
The signal for the piezoelectric actuators is generated by the platform and amplified by the CON100
amplifier module. An additional programming module (PDA) is needed to control the jet on time for the
Axiom platform only.
CAUTION! The jet offers a heated fluid area. The maximum temperature is + 100°C. The
drive is thermally isolated from the fluid area. This avoids temperature stress and
increases reliability and lifetime of the piezoelectric drive.
WARNING! If temperature exceeds + 45 °C, the operator assures appropriate labeling and
protection against contact.
Delivery of the fluid towards the jet takes place pneumatically or by a feed pump.
CAUTION! The jet must not be activated without fluid! Without fluid the valve seat can be
damaged with the risk of a seat leakage.
