Re-assembling the Unit 

 
Remove or add any relevant plastic blanking plates (safety cover) on 
the rear panel, by pushing out the push rivets from behind. 

To replace the rear panel,  angle the rear panel as shown to line up 
two location points with the floor of the recorder’s case. 

Reposition  the  shake-proof  washers  and  replace  and  tighten  two 
screws (Minitrend and eZtrend = M3 x 6, Multitrend = M4 x 8) at the 
top corners of the rear panel. 

If the recorder has been removed from the panel, refit the mounting 
clamps to the case in two opposite positions (Nema 4 positions) and 
secure into the panel. 

Minitrend  and  eZtrend  torque  setting  should  be  0.5  -  0.75Nm/4.4  - 
6.6lbf-in 

Multitrend torque setting should be 0.5 - 0.70Nm/4.4 - 6.2lbf-in 

 

 

Once  the  recorder  is  re-assembled  plug  the  CJC  sensor  supplied  with  the  board  into  the  centre  two  pins  on  the 
connector. If the CJC is not connected thermocouple inputs will not operate.
