Temperature Limits
Example 1
Requested temperature limit
τ
max
= 750 °C. The 8-pole code switch shows values
between “5” and “640”. Use a small screwdriver to set the “10”, “20” and “80” and
“640” switches to the right. The sum of the values gives the required temperature
limit
τ
max
= 750 °C
Example 2
Requested temperature limit
τ
max
= 420 °C. Use a small screwdriver to set the “20”,
“80” and “320” switches to the right. The sum of the values gives the required
temperature limit
τ
max
= 420 °C.
Example 3
Requested temperature limit
τ
max
= 146 °C. Use a small screwdriver to set the “5”,
“20”, “40” and “80” switches to the right. The sum of the values gives the required
temperature limit
τ
max
= 145 °C. An exact adjustment of 146 °C is not possible as
temperatures limits can only be adjusted in steps of 5 °C.
