1615/1199 Motor and Valve Travel Limit Adjustment
Instructions 1615-1199-1
QUICK REFERENCE INSTRUCTIONS
These instructions show how to change the valve travel limits in the 1615 actuator from the factory settings of 0 degrees minimum and 90 degrees maximum positions, to 20 degrees minimum and 80 degrees maximum positions. Actual positions will vary depending on your application. BEFORE adjusting travel limits: (see fig. 1) Observe that the actu- ator position scale is aligned with the actuator position indicating pointer at the “zero” position using the red scale. Also, observe that the actuator position indicating dial is also at zero and using the red scale. If the actuator position indicating dial is not at zero, gently rotate the indicator dial Clock Wise until it matches the actuator position scale and actuator position indicating pointer at zero.
1199 actuator and valve combinations are factory set to give full valve travel with full actuator travel. (0% actutator position = full closed; 100% actuator position = full open). The 1199 packaged assemblies are shipped in the 0% - full closed position and will open with increasing command signal (note: reverse acting as- semblies are shipped in the 0% full open position).
Valve travel limits are set by adjusting the travel limit switches inside the control actuator.
This “quick reference guide” should be used for applications that require changing the valve and actuator travel limits to some- thing other than the factory settings. When using the 1199 with a PLC control system, full close and full open travel limit may be able to be set in the PLC.
