4.25 Motor Thermostat
The thermostat setting may be customized:
1. Select “CHANGE MOTOR THERMOSTAT?” from the “SETUP” routine.
2. Select “YES” to enter the “MOTOR THERMOSTAT” display.
3. Select “NO” to choose between “ENABLED” and “DISABLED.”
In the “DISABLED” mode, the motor thermostat is bypassed and detection of an overheated motor does not prevent
operation of the actuator. This feature is user-selected when required by the application and may be desirable during
critical service.
NOTE: If the motor thermostat is disabled, third party certification including Factory Mutual, FM Canada, IECEx, ATEX
and warranty, will be voided.

4.26 Change Valve Data
“Change Valve Data” allows the user to identify the type of valve the QX actuator is mounted to.
• Select “YES” to “Change Valve S/N?” Then select “YES” to “ENTER DIGIT” displays.
• Select “NO” to choose the required number or letter for each digit of the valve S/N, up to a maximum of 16 digits.
• Select “YES” when the desired number or letter is displayed. When all digits have been entered select “YES” to
“RECORD S/N OK?”
• Follow same sequence for “CHANGE VALVE MODEL #?”, “CHANGE VALVE TYPE?”
• If “YES” to “CHANGE VALVE TYPE?” then “VALVE TYPE UNDEFINED-OK?” is displayed. “VALVE TYPE
UNDEFINED-OK?” is only shown until the valve type is chosen. In the rare event that the user would need to
“REINITIALIZE” the QX actuator, the screen will reappear. See Figure 5.1.
• The alphanumeric display scrolls from a symbol set, numerals and then A-Z in the following order: ! “ # $ % & ‘
( ) * + , - . / 0-9 : ; < = > @ A-Z. There is one blank at each end to enable a tag number with less than 16 digits to
be entered clearly. To highlight the digit being entered, a dot appears over the space and the letter above the space
disappears.
