Anti-condensation Heater
The heater warms actuators to prevent lubricant freezing and moisture damage.
● Not recommended if ambient temperature exceeds 35℃ (95℉).
● For large day/night or seasonal temperature variations, use with a thermostat is recommended.
Heater Thermostat
Heater thermostat switches off the heater when the internal temperature of actuators is higher than 25±5˚C (77±9˚F).
Auxiliary Limit Switches
Actuators come standard with two limit switches, LS1 for fully-open and LS2 for fully-closed positioning. Two auxiliary limit switches (LS3 & LS4) are optional for fully-open and fully-closed position feedback.
