Product Description:

The Vickers EEA-PAM-561-A-14 Power Amplifier is a small and durable component that is used to activate solenoids in hydraulic circuits. It has a maximum solenoid current of 1.8A and an amplifier input current of 1.4A when the input command signal is 0V. The maximum spool stroke is 10% with adjustment per direction of 0% to 50%. The adjustment per direction is made through a 2.5 - 10 / V scale, allowing users to make fine adjustments to improve the system performance. Due to the Operating temperature of 0 to 50 C (32 to 122 F), this amplifier is designed to function well in various working conditions. This makes it possible to use the equipment in cooler and even warmer climatic conditions of industries. It can work effectively without causing overheating or damage within the normal working environment and perform optimally at a variety of temperatures.

Another important advantage of the EEA-PAM-561-A-14 is the LED lights that facilitate easier operation of the system. There are three LED lights in the amplifier, which include green, red, and yellow. The green light signifies normal functionality, while the yellow light shows a precaution or some sort of unfavorable condition, and the red light suggests either a failure or a problem. All these indicators of the amplifier make it easier to identify any issues. This useful feature is crucial in the maintenance and proper running of the system.

It also offers various test facilities like valve test mode, controller test mode and auto operation mode for monitoring and diagnosing the system. With optically isolated digital outputs and position switches, this Power Amplifier is perfect for controlling hydraulic systems.

EEAPAM561A14

Symptom / LED Pattern	Likely Cause	Recommended Troubleshooting Step
Green “24 V” LED dark	Card not powered (supply < 20 V DC, fuse open, or polarity reversed)	Verify cabinet power-supply output, fuse, and wiring polarity; restore 24 V then repower the card.
Green “15 V” LED dark while 24 V LED is on	On-board logic regulator failed	Measure +15 V at test-jack z22; if 0 V replace regulator or the entire amplifier card.
Yellow “Enable” LED off even though PLC drives > +10 V to z24	Enable line actually < +6 V at pin z24 (broken PLC output or field wiring)	Trace/repair enable wiring, restore proper voltage, reseat card to reset latch.
Red “Overload” LED lit	Solenoid current > 1.8 A (shorted coil or wrong valve type)	Measure coil resistance, inspect cable for shorts, install correct coil; LED extinguishes automatically when fault clears.
Command signal present but valve will not move	Set-minimum or Gain* pots turned fully CCW*	Adjust both pots CW until monitor-jack MP1 shows ≥ ±0.5 V output, then test valve motion.
Ramp pots have no effect / valve jerks	Ramp-bypass link b12–b20 closed	Remove jumper or route it via a switch to re-enable ↑/↓ ramp generator.
Red “LVDT Fail” LED	Feedback transducer open-circuit or out-of-range	Check ±15 V sensor supply, inspect 6-pin LVDT cable, replace or re-align sensor, then zero PID loop.
PID integrator saturated (monitor-point MP6 pegged)	I-gain too high or feedback polarity reversed	Reduce I-gain trim, swap LVDT phase leads if needed, cycle power to clear integrator wind-up.
Card drops out when 24 V falls below ≈ 19 V	Undersized PSU or long cable run triggers low-voltage latch	Upgrade supply (≥ 40 W) and/or use larger conductors to reduce voltage drop.
All LEDs extinguish at cabinet temps > 50 °C	Internal over-temperature shutdown	Improve panel ventilation, relocate heat sources, allow card to cool below 45 °C before restart.
