❏ If QHLWKHUQXPHULFVQRUD" are displayed for the TEMP module, perform the
following actions:
6WHS Make sure there is a TEMP probe connected to the module. If not, connect one.
6WHS Make sure the TEMP parameter is turned on. Turn it on, if it is not.
6WHS Make sure the TEMP numeric is turned on. Turn it on, if it is not.
6WHS Make sure you don’t have too many TEMP module plugged into the module racks
you are using. If too many TEMP modules are plugged in, you get two status
messages: “Too many modules of the same type connected” and “Currently ignored
module in rack position x.x”. The last message enables you to identify the
supernumerary module.
These modules are ignored and should be removed.
6WHS Check the connection on the module and the rack interface.
 Unplug and re-plug the TEMP module and check if the green LED on the
TEMP module lights up after re-plugging. If it does not, proceed with the
following:
 Put the TEMP module into another slot and check the LED once again. If it
lights up now, the connector for the previous slot is faulty and the rack needs to
be replaced. If it does not, proceed with the following:

Replace the cable from the Satellite Rack to the function box. Again unplug
and re-plug the TEMP
module and check if the LED lights up. If it does not,
proceed with the following:
 Plug any other (not faulty) module into the same slot and check if the LED
lights up. If the LED of the alternative module lights up, the TEMP module is
defect and has to be replaced. If it does not, either the rack or the rack interface
card is defect. Proceed with the following:
 Replace the rack and plug in the TEMP module into the new rack. If the LED
on the module does not light up, replace the rack interface card in the function
box.
