4.7 Trouble-shooting concerning electronic circuit protector ESX300-S
The electronic circuit protector ESX300-S has two status LEDs allowing a comprehensive failure analysis in
the event of a failure. Please proceed as follows for trouble-shooting:
Important notes
Caution: Work with ESD protection
To protect electronic components against electrostatic voltage, any work must only be
carried out with corresponding ESD protection means. Failure to comply can cause
damages on the
ControlPlex
®
Rack system or the corresponding components.
Special precautions must be taken in the system or machine which reliably prevent an
automatic re-start of moveable parts of the system (cf. Machinery Directive 98/37/EG and
EN 60204-1, Safety of Machinery).
Note: ESX300-S time after short circuit or overcurrent trip
After tripping due to a short circuit, the circuit protector ESX300-S can only be reset after
a delay time of approx. 20 seconds.
Table 13: Hints for trouble-shooting for ESX300-S
What to do in the event of a failure
step action
1 Check status indication of ESX300-S:
Check the status of the LEDs of the ESX300-S by table 9, chapter 4.2.2
and put down the cause of the failure
2 Depending on the cause of the failure you can establish physical isolation
of the faulty circuit by pulling out the ESX300-S
See chapter 4.6 Removal of the electronic circuit protectors.
3 Remedy the cause of the failure
As described in step 1, e.g. short circuit on load
4
Re-install the ESX300-S after remedy of the failure
See chapter 4.5 Start-up of ESX300-S
