Diagnostics: No load voltage
You use this parameter to enable a diagnostic message about missing load
voltage.
In the absence of load voltage, only the diagnostic message of the affected power
module is forwarded to the DP master. The SF error LEDs of all the modules in the
affected potential group come on.
Diagnostics: Fuse blown
You use this parameter to enable a diagnostic message about a blown fuse.
In the event of a blown fuse, only the diagnostic message of the affected power
module is forwarded to the DP master. The SF error LEDs of all the modules in the
affected potential group come on.
Voltage type
You use this parameter to select the load voltage connected to the power module:
DC voltage or AC voltage.
The correct diagnosis is thus provided in the event of missing load voltage or a
blown fuse.
10.2 PM-E 24 VDC Power Module (6ES7 138-4CA00-0AA0)
Order Number
6ES7 138-4CA00-0AA0
Features
The PM-E 24 VDC power module monitors the supply voltage for all the
electronic modules in the potential group. The supply voltage is fed in by means
of the TM-P terminal module.
You can use any electronic module in the potential group of the PM-E 24 VDC
power module except the 2DI 120 VAC Standard, 2DI 230 VAC Standard and
2DO 24–230 VAC/1 A.
