Compax3 device description
192-120102 N7 - February 2004 49
Basic functions:
Compax3 devices disabled by:
Channel 1: Energize input (I0) to C3_1 (with powerPLmC) to "0" through open
contacts of Emergency power-off module (13 -14)
Channel 2: Enable inputs of individual Compax3's to "0" through open contacts of
Emergency power-off module (57 -58)
Activate Emergency power-off module
Before the Compax3 can be placed in operation, the Emergency power-off module
must be activated by a pulse to Input S33/S34.
Prerequisite:
! S3 closed
! Safety door closed: This is required before the safety door monitor enables the
Emergency power-off module via Input S11 (by closing the contacts between 23
and 24).
! Current flowing to K2 and K3
! K3: receives current if all Compax3's are currentless (contact closed in
currentless state) = Channel 2 feedback
! K2: receives current if all Compax3 devices are currentless (Output O0 = "1" if the
MC_POWER components of all devices have the status „FALSE“. ) = Channel 1
feedback
If S33 and S34 of the Emergency power-off module are briefly connected (pulse)
the contacts will be closed (between 13 and 14 and between 57 and 58)
Supplying current to Compax3
! The Enable input is activated on all Compax3’s by the Emergency power-off
module.
! Input I0 is also activated (="1") on Compax3 C3_1, which makes it possible to
activate the ENABLE inputs of the MC_Power modules with the AND modules. (If
a fault is still pending on Compax3, it must previously be reset. The
acknowledge/reset function depends on the type of the Compax3 device).
! Power is supplied to K1 and the mains power voltage is switched on by a K2
contact or by a closed safety door.
! The motors are energized with current.
Summary: Compax3 is not energized with current unless the feedback functions
via K2 and K3 are capable of functioning.
Case 1: Normal access to the hazardous area
Activate Emergency power-off switch
Disconnecting the connection between S11 and S31 /S32 (2 channels) deactivates
the Emergency power-off module and causes Contacts 13 - 14 to open
immediately.
Channel 1: The MC_POWER modules are deactivated for all Compax3's by Input
I0 = "0" on device C3_1 (with powerPLmC) via the AND modules. Compax3
devices are guided to a standstill and the current is switched off (by means of the
ramp for “drive disable) configured in the C3 ServoManager.
Channel 1 feedback: Output O0 = "1" if the MC_POWER components of all
devices have the status „FALSE“. .
