6.1 Start and control unit
E-PAK 150 DX/300 DX/500 DX has a start and control unit, see Figure 12. For
information about the different terminals, see the terminal connection diagrams
in Figure 25 (E-PAK 150 DX) and Figure 24 (E-PAK 300 DX/500 DX).
NOTE!
E-PAK 150 DX has a simplified start and control unit without Y/D
connectors and Y/D timer.
The start and control unit has the following components:
1. Transformer (TR1).
The transformer is a multi-transformer with terminals for several different
supply voltages, marked on the upper side of the transformer.
NOTE!
secondary voltage is always 24 V AC.
2. Reset relay (K5).
3. Transformer, primary fuses F2 and F3, both 6 A.
4. Timer for Y/D switching (K4T).
5. Y-contactor (K3).
6. D-contactor (K2).
7. Main contactor (K1).
8. Motor overload relay with manual reset button (S1F).
9. Grounding cables.
10. Emergency switch for 3-phase supply.
11. Terminals 1 and 2 for 24 V AC accessory supply. Fuse F5 on terminal 1,
1 A, fast.
12. Terminals 3 and 4 for the Pilot Signal (PS) cable. Fuse F6 on terminal 3,
1 A, fast.
NOTE!
13. Other terminals required by some accessories, all 24 V AC.
14. Transformer secondary fuse F4, 4 A, slow.
15. Filter Cleaning Relay (FCR). Normal settings: T
16. Start/Stop Relay (SSR) for automatic start and stop by means of a PS
cable. Normal setting=10 minutes.
17. Duty/Idle Relay (DIR) for automatic switching to idling mode. Normal
