Setting the High Setpoint Limits
You can protect your drying process by preventing someone from entering process
temperatures above an acceptable level for the material. You can also set the high
limit equal to the process temperature to prevent accidental or unauthorized
changes to the setting during operation.
1 Turn on the main power to the dryer.
2 While at the default screen (screen 5) press the scroll button and the (-)
minus button simultaneously to get to screen 14
3 On screen 14 enter the password for set up screens (754).
4 Scroll to screen 16.
This is your current high setpoint limit. Press +/- keys to set a new high
setpoint limit.
Tip:We recommend that you set your high setpoint limit 10° higher than your maxi-
mum high temperature setpoint to avoid unwanted alarms.
5 To lock in your new high setpoint limit and exit the password protected
screens, scroll back to screen 14,
then enter 500 and hit scroll.

system.
