Functions & Features

1) Emergency Override

In case of blackout, motor failure or overheat,  there is a built-in 2-way solenoid valve (DC12V) as a emergency release valve to lower the bollard.  You should have a DC12V backup battery in the control system, and a switch. The lowest operating voltage to  energize the solenoid  valve is 9V.

2)  Duty Cycle

TCP、TS and TP series are all intermittent duty cycle.  They can continuously working under intermittently condition, all weather.  The ambient temperature will cause duty cycle changed. Larger oil capacity tank and filling more oil will improve the duty cycle. Please consult us.

Furthermore, water cooling is an option to improve the duty cycle by submerged under water.

3)  Overheat/Thermal Protection

There is a thermal switch built inside to protect motor and system from overheat after continuously running.

4)   Hydraulic Fluid

We recommend low pour point hydraulic fluid when the unit will installed in cold area, such as  L-HV#22/32. Higher viscosity will effect the rising or lower speed.

5)  Bottom Support and Cushion

Please avoid the cylinder to support load when bollard retracted. Especially for those High Security version. It may caused the damage due to the impact from high speed lowering or running vehicle.  An optional “Bottom Cushion” will help to reduce the impact when bollard lowered to the end.
