19 Troubleshooting
19�1 General
19�1�1 POWER LED o, device unresponsive
The POWER LED in the bottom right will always be lit if the device is connected to the power supply.
If the LED is o, check that the power supply is connected properly as described in 2.3.1. Test the
voltage to check it is correct. If the LED still does not light up, the device may be damaged.
19�1�2 STATUS LED o, device not working properly
The STATUS LED lights up when the device starts up and begins running its scripts. Startup takes
about a minute, or longer if you have imported a le.
If the application script contains an error, the STATUS LED stays o and the device cannot run any
other scripts. As a result, it cannot operate any controllers. There may be a problem with the le, or
the le may use a dierent rmware version. Update the script, the rmware and – to make abso-
lutely sure – the device web pages.
19�2 Communication
19�2�1 Ethernet - no contact with the device� LINK LED o
The LINK LED should be lit if you have used an Ethernet cable to connect a WMPro to a running com-
puter, hub or switch. There are two types of network cable – straight-through and cross-over. If the
LINK LED fails to light up, either you are using the wrong type of cable, or the cable or the contacts
are damaged.
19�2�2 Ethernet - no contact� LINK LED on and LAN LED ashes sporadically
Check you are using the correct IP address. You can use an operator panel to check the IP address of
a device. Check you are using the correct PC settings as described in section 3.
Run the route print command in a Windows command prompt to check if you have used route add
correctly. Check for other devices in the network that are using the same IP address.
Is your WMPro using a gateway? See 3.3.
