Functions & Features
1) Automatic Stop
TCP, TS and TP series are avaiable for a optional built-in pressure switch. It is for automatic cutoff when cylinder extending or retracting to the end. It is good for avoiding system overheating from overload. We don’t suggest to use timer relay to stop the motor running.
2) 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.
4) Duty Cycle
TCP、TS and TP series are all intermittent duty cycle. they can continuously running in 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.
5) Overheat/Thermal Protection
There is a thermal switch built inside to protect motor and system from overheat after continuously running.
6) Internal Heater
There is a optional built-in heater inside the unit. Generally, the built-in motor will heat the oil in the initial cycles. Please conside it if the unit will be installed in a cold area. It will keep the oil warm to ensure the unit preform high speed in any time. The built-in heater will be cut off automatically when oil reach 45°C.
7) Hydraulic Fluid
We recommend hydraulic fluid L-HM#22 or #32 for TS, TP and TCP series product which used in vehicle bollard /barrier applications.
The low our point hydraulic fluid should be used if the unit will installed in cold area, such as L-HV#22/32. Higher viscosity will effect the rising or lower speed.
8) 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.
