BASIC OPERATIONS
POWER-UP
Upon power-up all displays and indicators are lit on for approximately 3 seconds. This is followed by the indication of the
controller model name on the Upper Readout and the firmware version on the Lower Readout, for approximately
1 second.
MAIN DISPLAY MODE
After the Power-up display sequence, the Upper Readout starts showing the Temperature Value in °C and the Lower Readout
indication depends on the autoclave cycle state (described below). This is the MAIN Display Mode that shall be used most
often.

Step 0 (Idle State - Start Command Awaited)
The Lower Readout shows the message (Start). The front panel indicators S and P are off. The heater is kept OFF and
the air outlet is kept ON. Use either front panel ‘ENTER’ Key or back panel Remote Key to issue ‘Start’ command to initiate a
new autoclave cycle.
Step 1 (Temperature Raised to Air Outlet SP)
The Lower Readout shows the Control Setpoint value. The front panel indicators S and P are both on, indicating that the SP
value is being shown on the Lower Readout. Both the heater and air outlet are maintained ON. As soon as the Temperature
reaches the Air Outlet SP, the air outlet is turned OFF.
Step 2 (Temperature Raised to Control SP)
The Lower Readout shows the Saturated Steam Pressure value in either Kg/cm² or PSI after the temperature crosses
100.0 C. The front panel indicator S is off while P is on, indicating that the Pressure value is being shown on the Lower °
Readout. The heater is kept ON until the temperature reaches the Control SP. As soon as the temperature reaches the Control
SP, the soak timer starts counting down. (For the detailed Soak Timer operation, refer Section 5 : Soak Timer Parameters.)
Step 3 (Temperature Maintained at Control SP)
The Lower Readout shows the balance Soak Time in Minutes:Seconds format. The front panel indicator P is off. The indicator
S flashes if the timer is counting down and glows steadily if the timer is in hold state. The heater is appropriately switched ON
and OFF to maintain the temperature at Control SP while the Soak Timer is counting down to 0. During this time the Saturated
Steam Pressure value can be viewed by holding the UP or DOWN key pressed.
Upon completion of Soak Time, the cycle ends and the controller re-enters Step 0 (Idle State).
