PR-DTC-3000 Type
The unit can be seriously damaged by the wrong connection (observe the diagram of load connection) of the power
terminal, contacts between the DC input/output wiring and power line, and the short circuit of the output line.
Before supplying power, ensure the appropriate connection between power and grounding, and the input/output wiring.
Precaution
: Check power input and wiring
1) Output ON/OFF (OUT Input Terminal)
-
When the Remote Out is On, the control output is generated irrespective of [Out ON/OFF Button] on the panel.
- When the Remote Out if Off, the [Output ON/OFF Button] on the panel becomes valid, and each time the
button is pressed, the control output changes ON → OFF → ON.
2) Diameter Preset (RSD Input Terminal)
- As the initial diameter set when the Remote RSD is On is preset as the reel diameter, the measurement of the
reel diameter becomes initialized.
3) Unwind/Rewind (BWD Input Terminal)
- When the Remote BWD is On, the diameter measurement does Rewind to add diameter.
- When the Remote BWD if Off, the diameter measurement does Unwind to subtract diameter.
4) Emergency Stop (STP Input Terminal)
- When the Remote STP is On, the rate set at the STP is produced in proportion to the immediately preceding
output.
5) Calculation of the Diameter
- The unit always calculates the diameter based on the signals from the proximity switch.
- Based on the calculation, the control output adds at Rewind, and subtracts at Unwind.
