SECTION 3 – OPERATION 3-3
Running the Test
If necessary, press the RESET button to reset the TEMPERATURE LIMIT ALARM.
Make certain the FILL CYLINDER switch is in the ON position; the HEATER switch is in
the ON position; and the COOL CYLINDER switch is in the OFF position.
Also make certain the CYLINDER DRAIN valve is closed and the cylinder is filled with
water.
Program and start the Temperature Controller.
Use the PRESSURIZE CYINDER switch to increase the cylinder pressure to the desired
level, if necessary. The PRESSURIZE CYLINDER switch may be left in the ON position to
maintain a minimum pressure if the PUMP PRESSURE ADJUST regulator has been set as
outlined in the
Pressure Control section.
If Temperature Limit Alarm Occurs
If the cylinder exceeds its maximum operating temperature, a TEMPERATURE LIMIT
ALARM will occur. When this alarm occurs, the yellow pushbutton switch will light and the
heaters will cease to operate. The only way to reset this alarm is by pressing the lighted
switch on the front panel. If a TEMPERATURE LIMIT ALARM occurs, the instrument
should not be operated again until the reason for the alarm is found and corrected.
Cooling the Cylinder
The 7360V Vertical Curing Chamber is equipped with internal cooling coils for rapid
cylinder cooling at the completion of a test. The following is the procedure for cylinder
cooling.
1.
Make certain that the PUMP PRESSURE ADJUST regulator has been set so that
pressure in the cylinder is maintained at 1600 psi/11 MPa or greater until the temperature
of the cylinder is below 200°F/93°C. This will prevent water in the cylinder from
flashing into steam.
2.
Turn the PRESSURIZE CYLINDER switch to the ON position if it is not already in the
ON position.
3.
Turn the HEATER switch to the OFF position.
4.
Turn the COOL CYLINDER switch to the ON position.
5.
Press the F1 button (Automatic / Manual Mode) on the Temperature Controller.
