New PDU (UL Certified)
New Safety Relay
New Safety relay K3 (the same relay type used for activating the Drying System) for the drivers replaces the old problematic one.
The K3 relay has been moved to a new position, and the RL3 relay is installed into its place(see Figure 4).

New Main 3-phase Circuit Breaker
The main Circuit Breaker F1 (see green line) includes the Switch Tripped mechanism (terminals 9,10). The two phases are connected (see dashed green line) via the Emergency Switch.
When the Switch Tripped is powered, the F1 contacts are closed and the machine is connected to the power line.
When the Emergency Switch is pressed, the Switch Tripped is powered off and the F1 contacts are opened; i.e. the machine is disconnected from the power line.

New Emergency Stop Button
The new PDU is equipped with its own Emergency Stop button
When pressed, the RL3 relay is activated and the electrical power is disconnected before the Main3-phase Circuit Breaker and from the UPS to the machine – see Figure (next slide).

The green dash line marks the circuit UPS Emergency Switch RL3 coil UPS. When the Emergency Switch is pressed, this circuit is opened.
The cyan dot line specifies the circuitUPS RL3 contacts Drivers Left Cabinet (PC, Power Supplies) UPS. When the Emergency Switch is pressed, this circuit is opened.
The magenta dot line specifies the self-sustain loop for holding the RL3 powered in case of general electric failure(i.e. Switch Tripped is not powered and the green circuit is opened).
