Press Start/Stop key
under working interface. The pump operation
indicator is on. The auxiliary display shows the compressor protection
countdown. After countdown finished, the compressor begin to run, and the
auxiliary display shows the target temperature., and the cooling indicator will
indicate cooling state according to the computing result of the PID modifier.
Press Start/Stop key
to stop operation during unit operation, and the
unit enters into standby mode.
In normal operation state, the auxiliary display on the control panel shows the
target temperature, the main display shows the current temperature value of
the circulation liquid.
3.3.4 Start/Stop pump
The pump indicator is off state when pump does not work. Press Pump key
to start, the pump indicator lights on. During pump is working, pump
operation indicator is always on state until the pump stops.
Remark: In the unit working state, the pump will continue working to
provide bath liquid circulation, it is invalid to stop the pump by pressing
the Pump key
.
3.3.5 PID Adjustment
When medium circulator works under different temperatures, the control
parameters are slightly different if cooling power is different. When
connecting with different loading units, the control parameters are usually
different. PID parameters can be adjusted via circulators for much more
precise temperature control.
Adjustment process:
First set the target temperature then press Start/Stop
key
. Long press Enter key
until the auxiliary display shows the
adjusting objective and adjusting state alternatively. At this moment, users
need not do any operation. When adjustment finished, the system will quit
automatically and enter into operating state. If users want to quit the
adjusting state, long press Esc key
, then the unit back to operating
state.
