"The gate panels move in the wrong direction."
1. Check hose connections to verify the correct order red to red and brass to brass.
2. With the system engaged to open, verify that the Open Valve coil develops a strong pull. (This
can be tested by removing the nut retaining the coil and grasping the coil)
"The gate only opens or only closes."
1. If the gate only opens, the directional valve may be stuck and need cleaning or replacement.
2. If the gate only closes, the valve coil is not being energized, or is defective.
"I have a bi-parting gate system and the gate
panels won’t synchronize.”
1. Air trapped in the hydraulic system can cause slow or jerky movement and prevent the panels
from synchronizing.
2. Refer to General Maintenance and read the instructions for bleeding air from the SwingRiser
hose which is found in the Hydraulic section.
“The gate panels move very slowly and seem to shudder throughout gate travel. ”
1. Air trapped in the hydraulic system can cause slow or jerky movement.
2. Refer to General Maintenance and read the instructions for bleeding air from the SwingRiser
hose which is found in the Hydraulic section.
GATE SPEED:
The speed in which a hydraulic operator moves a gate is determined by the size of the pump and
the size of the actuator components. Just like a gear box, this speed is not adjustable. Attempting to slow a gate by
changing any valve setting will cause a great deal of inefficiency and heat. If the speed of a gate must be changed,
contact your HySecurity distributor. Extremely cold weather is unlikely to seriously affect the speed of the gate,
because HySecurity employs a special grade of hydraulic oil that we call UNIFLOW oil, which maintains a very
linear viscosity over a broad range of temperatures. Because of this high quality oil and other design
considerations, we rate our operators for service in ambient temperatures of
–40F degrees to 130F degrees. If the
speed of your operator has been affected by cold weather, verify that the gate hardware is not impaired by ice and
verify that the reservoir it is filled with UNIFLOW oil. In severe conditions, consider adding a heater.
