Fig. 3 2. Overview, functional description 2.1 Design Fig. 1 Rear side Legend to Figure 3: Control unit for industrial lubrication systems 1 Terminal strips 2 Circuit board Figure 1 shows an SKF compact lubrication unit with a control 3 Service interface unit installed in it The rotary switch for setting the parameter values is located on Fig.
2.3.3 Overview The operating time SKF control units available for single-line systems, and their Once the interval time is finished, the control unit initiates the functions lubrication procedure (also called "operating time"). The operating time is made up of the monitoring time (TU) and the Table 1 pump delay time (TN).
2.4 Terminal assignment 2.4.3 Inputs Fig. 4 All inputs and also the 24 V supply connections are galvanically isolated from the operating voltage (L1, N) and from the outputs of the relays d1 and d2 2.4.4 Outputs All the outputs are relay contacts. They are dry contacts, galvanically isolated from the operating voltage, with the exception of terminal 12.
3. Technical data Table 4 Technical data Designation Value Nominal input voltage Un AC (100..120) V or AC (200..240) V Rated input voltage 0.85 Un to 1.1Un (85..132 V / 170..264 V) Nominal frequency 50..60 Hz Rated frequency 49..61 Hz Release value Max.
4.4 Storage temperature range 4. Delivery, returns, storage For parts not filled with lubricant, the permitted storage 4.1 Delivery temperature is the same as the permitted ambient temperature range (see “Technical data”). After receipt of the shipment, it must be inspected for any shipping damage and for completeness according to the shipping documents.
