 Posted: 11/08/2018 18:07 Post subject: CPE400 GE CONNECTED TO DIRECT POWER SUPPLY |
 |
|
i have CPE400 GE cpu all LED blinking continuosly and the ENERGY PACK ACC403 is not working therefore i want to run the CPE400 without the ENERGY PACK. I connected the 24Vdc power supplt to input connector at CPE400 and disconnect the ENERGY PACK but the CPE400 not power-up
My question is why not power-up the CPU and how we solve this.
Advance thanks and
Regards, |

The user-supplied SELV3 power supply must supply voltage in the range of 18Vdc to 30Vdc
Did you check it?
The CPE400 may experience an inrush current of up to 49A for 15μs
In the CPE400, the voltage to the inner loads is clamped to 33Vdc. At 33Vdc, the internal clamping diode starts conducting at 1mA. Any further increase in the voltage will cause the internal current fuse to blow and/or the clamping diode to break
Overcurrent protection
The function protects the internal circuitry from overcurrent conditions before serious damage can occur, such as overheating of the equipment. The fuse is rated for 4A continuous current. Once the sensed current reaches 40A, the fuse will blow after a period of 10ms to 100ms.
3.
You Will Need: 3.1.
• This PACSystems Rackless RX3i CPU.
• A compatible SELV 24Vdc, 48W power supply (72W if Energy Pack attached).
• (Optionally) A compatible Energy Pack, IC695ACC403, and corresponding cable.
• If no Energy Pack is to be attached, use the power supply cable described in Section 2.4.
• A DIN rail, typically mounted in an enclosure, as discussed above. Alternately, mount the unit using the compatible panel-mount adaptor.
• A computer running Proficy Machine Edition (PME) configuration and programming software. PME Version 9.00 SIM 8 or later supports the CPE400.
• Ethernet cable for connecting the PME programmer computer to the CPE400.
• Additional cables, as needed, to connect each port employed in the application.
• A very small slotted screwdriver to secure the 24Vdc mating connector.
• A T8 Torx screwdriver, if the micro-SD slot cover is to be removed. Note that the cover must be replaced to achieve immunity from electrical noise.
• A T10 Torx screwdriver, if exchanging the mounting adaptors
3.2.
For startup and configuration of the CPE400, complete the following steps. For full details on CPE400 operation, refer to the PACSystems RX3i and RX7i CPU Reference Manual, GFK-2222Y or later.
1. Mount the CPE400, as described in Section 2.2 and per the Installation and Maintenance Requirements document, GFK-3004.
2. Attach the user-supplied power supply cable as described in Section 2.4 if no Energy Pack is being used.
3. (optionally) Mount and attach the compatible Energy Pack, IC695ACC403, as described in the PACSystems RX3i Rackless Energy Pack IC695ACC403 Quick Start Guide, GFK-3000.
4. Turn on the power supply unit: the unit should then run without the need to press any buttons.
5. If not previously configured, configure the RX3i PLC using PME 9.00 SIM 8 or later, as described in the Configuration section below.
Note: When the ACC403 Energy Pack is powered up, a finite period is required to charge it up to its operating level. During this time, the Energy Pack will indicate this condition via its LEDs (refer to the PACSystems RX3i Rackless Energy Pack IC695ACC403 Quick Start Guide, GFK-3000).
The CPE400 will begin its boot cycle immediately upon power application. However the embedded controller will not start its control until the ACC403 is charged. This typically takes 45 seconds or less. In the event the ACC403 is faulty or is not communicating, CPE400 commences operation without the Energy Pack.
Note: In the event of loss of power, with the ACC403 Energy Pack connected and charged up, the CPE400 remains on for 4 seconds to backup user memory into its non-volatile memory.
The only way to recover from this condition is to power cycle the PLC without the CPU energy pack/battery connected.
Perform the following sequence below.
CAUTION: This clears the PLC RAM memory. Ensure you have a backup of the project before proceeding.
1. Power down the PLC.
2. Remove the CPU battery or energy pack and leave it disconnected.
3. Power up the PLC and wait for CPU to power up correcty. Once the CPU OK LED is solid green, it has passed power up diagnostics.
4. Reconnect the CPU battery or energy pack and then redownload the project to PLC. |

Thanks very much
I opened the CPE400 module and checked the internal fuse,and found fuse OK, but the link in Negative line found blow(open ) Is it possible to Weld for temporary use?. |

well..check before what is the cause??
It was a wrong fixture on screw or the isolation resistance is the problem??. |
