When   the   T257P   Chiller   is   operating   and   providing   temperature   controlled   fluid   it   is   said   to   be   in   the   
RUN   Mode.      During   the   RUN   Mode   the   screen   content   shown   in   figure   5-­‐1   is   displayed.         The   RUN   
Mode   screen   shows   the   instantaneous   fluid   temperature,   the   maximum   and   minimum   temperature   
stability    over    the    past    60    minutes,    the    set    temperate;    the    sensor    used    to    control    the    fluid    and    if   
applicable,   the   coolant   flow   rate.

How   to   Stop   and   Start   the   T257P   Chiller   

5.1

1.

 

To   stop   the   T257P   Chiller,   press   the   “Stop”   button.      This   will   place   the   system   in   standby   mode   
with   the   coolant   pump   and   the   temperature   control   subsystem   in   idle   state.   

2.

 

The    fans    will    continue    to    operate    for    some    time    to    cool    the    heat    sinks.        Once    the    heat    sink   
temperature   is   near   ambient   the   fans   will   enter   the   idle   state.   

3.

 

To    Start    the    T257P    Chiller,    press    the    “Start”    button.        This    will    display    the    RUN    Mode    screen   
with   the   chiller   controlling   the   fluid   to   the   previous   set   temperature.
