2. External Trigger : An input used to start a sampling
or pole measurement. The measurement type can be
selected in the ZOOM Configuration software.
•
Input type: 10 kΩ pull up resistor to 24 Vdc;
•
Control type: dry contact or electronic switch.
Triggers on a falling edge.
•
Voltage threshold: 3.7 V
3. Acquisition Trigger : a bi-directional port used to
allow a master ZPU-5000 unit equipped with an air
gap sensor to share a 1/pole reference signal to
slave ZPU-5000 units not equipped with an air gap
sensor.
This is all configurable in the ZPU-5000’s properties
with the help of ZOOM Configuration.
4. Rotation : an input used to indicate the unit’s rotation
direction (pumped-storage units) and select the
appropriate synchronization probe. A more precise
configuration is possible in
ZOOM Configuration

•
Control Type: dry contact or electronic switch.
Control contact: open = SYNCHRO 2 IN;
Control contact: closed = SYNCHRO 1 IN.
•
Voltage threshold: 3.7 V.
