Internal low voltage supplies:
24V DC
Shutter motor
4.4.2. Indicators
The e-Brick has two LED indicators on the rear panel, one to show that the internal 24V
supply is on; the second indicates that the main contactor (K1) is enabled and that the e-
Brick output is on.
4.4.3. System Emergency stop
The e-Brick can only be enabled if the system emergency stop (E-stop) contacts on the
Press connector [P1] are closed, enabling the internal safety relay. The internal controls
monitor the E-stop status using auxiliary contacts on the safety relay; as a safety measure,
the relay can still disable the supply in the event of a control failure.
Warning!
Refer to 5.4 for essential safety information relating to E-stop usage.
4.4.4. Contactor
The 3phase power to the main converter in the e-Brick is switched on using an internal
contactor. By design, the contactor coil can only be energised when the press E-stop is
enabled and a second relay is switched on. The second relay is switched on by the
embedded controller and is enabled from the HMI screen.
4.4.5. Temperature & cooling
Fan failure detection
Internal temperature warning
Over temperature trip
4.4.6. Output protection
Voltage limit
Current limit
Short circuit protection
Warning!
Under no circumstances should either lamp output terminal be electrically connected
to chassis ground; this will invalidate the e-Brick warranty and is likely to result in severe damage
to the e-Brick.
