HBC-4301 Operators Manual - Novatech Controls

1. Press the SETUP button to enter the setup mode.
2. Use the Function keys to find the setup function #20. Select Automatic mode. Press
the ENTER button.
3. Go to setup function #22. Set the vacuum level in kPa. Press the Enter button.
4. Press the SETUP button to return to the RUN mode.
The control case will now attempt to control the pumping rate of vacuum pump #2 to
maintain the set vacuum pressure. If the leak rate of the repair is very small the pump may
stay off operate for a few occasional pump cycles. If the leak rate of the repair is high the
leaks should be plugged. A high leakage rate wastes energy and causes the pump to operate
unnecessarily.
NOTE: If the leak rate is less than 0.1 l/min at a low control vacuum (i.e. less than -45kPa,
13.3 Inches Hg) the vacuum pressure may vary by 6 kPa or 1.8 Inches Hg.
Providing a leak of 0.3l/min will allow better control of the vacuum at low vacuum levels.
7.5.3 Automatic Mode, Programmed Vacuum Levels
In Local mode, when running a temperature cycle from the control case, the vacuum will
follow the vacuum steps set in setup #9, 11, 13, 15, 17 and 19. Automatic vacuum mode
must be selected in setup function #20.
7.5.3 Vacuum Alarms, Local mode
1. Press the SETUP button to enter the setup mode.
2. Use the Function keys to find the setup function #24, ENABLE VAC ALARM.
Select Yes and press the ENTER button.
3. Go to setup function #25 and select the sensor that is to be used for the alarm.
4. Go to setup functions #26 and #27. Set the vacuum level in kPa for the high vacuum
and the low vacuum alarms. Press the ENTER button.
The alarm will be active if the vacuum level is above or below the vacuum set level by the
amount set in setup functions #22 or #26 and #27.
5. Press the SETUP button to return to the RUN mode.
