Page 3: Working Principle
1 – Working principle DPSK micro controlled planarity indicator is a digital device capable of: 1. operating as a common planarity indicator, living as an output axis X and Y planarity, separately over a 360° degrees range; 2. giving as an output X and Y planarity for two half axis each, allowing DPSK to be used for auto-levelling or other (optional) functions. -

4- Electrical connections 4.1 Preparation Cable choice To avoid any dysfunction due to incorrect wiring, device shall be cabled granting optimal electric insulation of all parts accessible by unspecialised operators ( insulating resistance > 1G x cm). Mounting must avoid improper cable bending, traction, twisting pressing or squeezing during machine operation. - Page 7 4.2 Supply Cable colour Description Function WHITE Positive supply + 7 ... + 30 Vdc YELLOW Negative supply 4.3 Planarity output (Relay) Cable colour Description Function BLUE Common relay GREEN NC Relay Normal closed GREY NO Relay Normal open 4.4 Serial RS232 communication Cable colour Description Function...
- Page 8 5- Calibration and setting using RS-232 connection 5.1 Zero Device zero is factory-calibrated. An after-mounting zeroing is preferable in most of the cases. Zero can be achieved in two ways: 5.1.1 – using the following RS-232 specific command (via Hyperterminal-like program): ZERO <...
- Page 9 5.3 Switching delay interval Switching delay interval are easily selectable using RS-232 commands between 0.1 and 25.5 seconds. Delays are selectable using RWAIT command (delay before intervention: waits X seconds to activate alarm) and FWAIT (delay after intervention: waits X seconds to deactivate alarm). RWAIT=22 <...
