Opening the E-651 Housing
Should it ever be necessary to open the E-651 housing, e.g. for
a static gain adjustment procedure, proceed as follows:
1
Switch off the controller and disconnect the power
supply.
2
Use a Torx 8 driver to unscrew the 2 screws in the blue
frame on the rear panel and carefully remove the rear
panel.
3
Use the Torx 8 driver to unscrew the 2 screws in the
blue frame on the front panel. Carefully remove the
front panel, which also pulls the PCB out of the housing
(the rear panel must be turned and pulled carefully
through the housing too).
4
Reconnect the power supply to the socket on the rear
panel. Keep the system powered down.
Note that some adjustment elements on the main board and on
the E-801 and E-802 submodules are covered with sealing
lacquer. Damage to the seal will void the warranty except in
consultation with PI.
