Using the Automatic Slave Function 47
User Guide v 1.4 — September 2015 Making Adjustments
Based on the comparative data stored, the system knows which zone to slave the faulty zone
to so that it continues to operate in a closed loop control mode. On the Home screen the
auto-slaved zones number will switch between the slaved zone number and the master zone
number.
7.3.4.2 Using the Automatic Slave Function
The only requirement as the operator is to see the error, Clear and Reset the alarm. The
moment this is done, the slave data will be permanently stored to that zone.
Once a zone is Slaved, the auto-slaved zone's name and number, on the Zone Data screen,
will switch between the slaved zone number and the master zone number. The master zone's
name and number will be displayed in Blue.
In the event the automatic slaving function was unable to find a suitable partner it would
pass onto the Automatic Manual Control (AMC) function. AMC allows the system to
automatically switch the bad zone into manual mode.
7.3.4.3 Manually Slaving One Zone To Another
If a thermocouple is about to fail you can manually slave it to another zone before it fails
completely.
NOTE:Neo2 must be in Advanced mode to change this setting. Refer to Section 4.2.1.
To manually slave one zone to another:
1. On the Quick Set screen, touch the zone to change.
To select more than one zone, touch the additional zones and they will be selected.
2. Using the Parameter Scroll buttons, scroll to SLAVE.
3. Touch SLAVE and a numerical Key window appears.
4. Enter the zone number to Slave the faulty zone to, and then touch Enter. Make sure to
pick a zone with similar heater characteristics, do not slave a manifold zone to a tip zone.
A zone cannot be slaved to itself, if it is attempted, Neo2 will ignore it.
Once the Slave for a zone is not required, touch SLAVE and enter 0 in the numerical key
window and the slave assignment will disappear (--).
5. Touch OK.
