Why won't the actuator stem move on demand in my Samson Controller?
The actuator stem might not move on demand due to several reasons. It could be blocked; in this case, check the attachment and remove any blockage. Another cause might be insufficient signal pressure, so check the signal pressure and the signal pressure line for leakage.
What to do if the actuator stem doesn't stroke through its complete travel range on a Samson 3271 Controller?
If the actuator stem does not stroke through its complete travel range, it could be due to insufficient signal pressure. Therefore, check the signal pressure and the signal pressure line for leakage. Another possible cause is incorrect setting of valve accessories, so check the actuator without valve accessories and then check the settings of the valve accessories.
