Pressure Relief Valve
1. Purpose
A. Limit the maximum pressure in the hydraulic system to a safe level.
B. Keep the motor amperage (and battery drain) at a minimum when the cylinders dead
head (reach full stroke).
2. Adjusting Relief Valve (on the pump)
Note:
In general, do not adjust the relief valve. It is set to the correct operating pressure at
the factory.
A. Symptoms of incorrect pressure relief adjustment.
1) Relief pressure too high
a. Battery current draw is excessive
b. Motor RPM is slow
2) Relief pressure too low.
a. Motor RPM is fast
b. System will not fold (cylinders will not extend).
c. Excessive turbulence in reservoir.
Note:
On applications where a hydraulic component is being replaced, contact Energy
Absorption Systems Customer Service Department to purchase replacement parts.
Warning:
Do not exceed pressure rating for hydraulic system components! System
pressure is set to 2400 psi at the factory.
Counterbalance Valve
1. Purpose
The counterbalance valve allows free flow of hydraulic oil into and out of the cylinders but
blocks the flow when there is no pump pressure. The counterbalance valve locks the
system when the pump is not running.
Warning:
When the system is stopped at an intermediate angle, there will be
pressure on the oil in the hoses between the counterbalance valve and cylinders!
This pressure is supporting the load of the folding bay! ALWAYS make sure the TMA
is completely folded or completely unfolded before loosening a hose fitting or
servicing any check valve! This will minimize the chance of injury from an
uncontrolled falling load or spray of high-pressure oil. Never stand underneath the
TMA when performing any sort of service or checking any component of the system.
