Flowserve TRS 5-6 - Manual (Page 12)

12
On the rear of the TRS 5-6 there is a code switch for adjusting the temperature.
Adjusting Temperature Limit
Example 1
Requested temperature limit
τ
max
= 176 °C. The 8-pole code switch shows values
between “2” and “256”. The basic temperature is 30 °C. Set the “2”, “16” and “128”
switches to the right using a small screwdriver. The other switches remain in their
left hand position. The sum of the three values gives a temperature of 146 °C, plus
the basic temperature of 30 °C. This corresponds to the requested temperature limit
τ
max
= 176 °C.
Example 2
Requested temperature limit
τ
max
= 446 °C. Set the “32”, “128” and “256” switches to
the right using a small screwdriver. The sum of the three values gives a temperature
of 416 °C, plus the basic temperature of 30 °C. This corresponds to the requested
limit temperature
τ
max
= 446 °C.
Example 3
Requested temperature limit
τ
max
= 79 °C. Set the “16” and “32” switches to the right
using a small screwdriver. The sum of the two values gives a temperature of 46 °C,
plus the basic temperature of 30 °C. This corresponds to a limit temperature
τ
max
= 78 °C. An adjustment of 79 °C is not possible as temperatures can only be
adjusted in steps of 2 °C.
