Page 25: Input And Output Signals - External Control (Plc)
Input and output signals - external control (PLC) LUB-D operates as a pulse-controlled lubrication system only if unalterable input signals (high level) are transmitted from the PLC to LUB-D via PIN 2 in a defined sequence. LUB-D signals the respective status to the PLC via high/low levels which can be tapped off at PIN 4 and thus enables comprehensive control or, by suitable programming of the PLC, differentiated evaluation of the different states. To integrate LUB-D into an external control one input and one output must be provided on the control side. -
Page 26: Input Signals
Input signals LUB-D provides the following unalterably defined control signals (input signals) which must be transmitted from the PLC to LUB-D via PIN 2 of the electrical M12x1 interface as high level (+24 V DC). The control signals must be generated as high level (+24 V) by the external controller (PLC) over certain times with a tolerance of +/- 0.1 seconds. -
Page 27: Control Signal 2 Seconds
8.2.1 Control signal 2 seconds The control signal 2 seconds triggers a single dispensing process at pump body 1. After a specified pause time this control signal can be repeated or another control signal can be sent. The operating states are output by LUB-D via PIN 4 as a high/low level and must be tapped and processed accordingly by the PLC. - Page 28 Description: LUB-D is properly connected to an external controller via the electrical interface and connected to the power supply. LUB-D sends a permanent output signal (high level) to PIN 4 which indicates to the external control (PLC) that it is ready for operation. This output signal must be perma- nently and continuously present for >3 seconds to control LUB-D by a PLC.
-
Page 29: Control Signal 5 Seconds
8.2.2 Control signal 5 seconds The control signal 5 seconds triggers a single dispensing process at pump body 2. After a specified pause time this control signal can be repeated or another control signal can be sent. The operating states are output by LUB-D via PIN 4 as a high/low level and must be tapped and processed accordingly by the PLC. - Page 30 Description: LUB-D is properly connected to an external controller via the electrical interface and connected to the power supply. LUB-D sends a permanent output signal (high level) to PIN 4 which indicates to the external control (PLC) that it is ready for operation.

After a certain pause time this control signal can be repeated or another control signal can be sent. The operating states are output by LUB-D via PIN 4 as high/low levels and must be tapped and processed accordingly by the PLC. - Page 34 Description: LUB-D is properly connected to an external controller via the electrical interface and connected to the power supply. LUB-D sends a permanent output signal (high level) to PIN 4 which indicates to the external control (PLC) that it is ready for operation. This output signal must be perma- nently and continuously present for >3 seconds. This condition must be fullfilled to control LUB-D by a PLC.
-
Page 35: Control Signal 14 Seconds
8.2.5 Control signal 14 seconds The control signal 14 seconds is used to acknowledge error messages. It is the only control signal that LUB-D can process when a low level output signal is sent. Regardless of the basic principle of remotly acknowledging an error it is essential to identify and eliminate the cause when an error message is present. - Page 36 Description: LUB-D is properly connected to an external controller via the electrical interface and connected to the power supply. There is an error at LUB-D. LUB-D sends a permanent output signal (high level) to PIN 4 which indicates to the external control (PLC) that it is ready for operation.
