The start temperature is approached with the desired ramp (see program 21).<br />

The LCD display displays the following message during this time:<br />

22 int<br />

22.1°C ts 2.8<br />

The first line is the actual internal value, in the second line the given set point. ‘ts ’ is the<br />

required time, which the start ramp has still to run. The time ‘ts ‘ is given in minutes.<br />

The actual value should be the same as the start temperature if ts = 0.<br />

A waiting time tw is displayed if the difference is larger than +/-1K. In this time it is heated<br />

up to starting temperature. The following will be displayed if the difference between starting<br />

temperature and actual value is smaller than +/-1K:<br />

or<br />

TP gestartet!<br />

TP: temp-stabil<br />

Segment 1/1<br />

The number before the oblique is the number of the tempering program, and the other is the<br />

segment number.<br />

The LCD display now displays the following message:<br />

21 int t p 212<br />

21.7°C t s 7.5<br />

21 int internal actual value<br />

21.7 °C Set point<br />

tp 212 remaining run time of the tempering program in minutes (or hours, see progr. 27)<br />

ts 7.1 remaining segment run time<br />

If ‘!!!’ appears with tp or ts , it is not possible to display the time (more than 54 hours).<br />

The program will still be run as normal. If the segment time is run out and the actual value is<br />

not the required end temperature (+/-1K), ts can appear in place of tw (waiting time).<br />

This condition can only be adjusted for the tempering program when the status is<br />

‘temperature stable’. At the status ‘time stable’ it will switch straight on to the next segment<br />

without regards to the actual value. Occasionally information will be provided about the<br />

current status of the tempering program and the given segment, so that the operator does<br />

not loose track of progress during a long program run.
