Product Description:

This robust power amplifier card EEA-PAM-533-D-32 operates with a maximum solenoid current of 2.7 A and has an amplifier input current of 0.3 A at 0 V command signal (MP1). The card offers short-circuit protection for all outputs.

The EEA-PAM-533 amplifier card is powered by a nominal 24V DC power supply with a power output of 50 W, ensuring efficient and stable operation. The voltage range for the power supply is between 20 V and 40 V, with protection against reverse polarity. The signal sources for the model include 15 V and 10 V options, accommodating a variety of control signals with maximum peak-to-peak ripple specifications of 50 mV and 20 mV, respectively. The models temperature drift is minimized to less than 1 mV/C, ensuring stable performance across a wide operating temperature range of 0 to 50C (32 to 122F). The factory setting for ramp-time adjustment is approximately 50 ms, with adjustable ranges from 50 ms to 5 s. The EEA-PAM series amplifier card supports direct and inverting voltage inputs ranging from 0 to 10 V and current inputs from 0 to 20 mA. The input impedance is set at 47 k for voltage and 100 for current.

The EEA-PAM-533-D-32 features a deadband compensation adjustment per direction of 0 to 50 % of the maximum spool stroke from the centered position allowing for precise control and minimizing dead zones in valve operation. The model accepts command inputs in both voltage and current forms. The model includes factory-set dither and gain adjustments, with a gain adjustment range per direction of 2.5 to 10% per volt. Wake Industrial has this Vickers card in stock and offers a 1-year warranty upon purchase.

Symptom / LED or Test-Jack Reading	Likely Cause	Corrective Action (Troubleshooting Step)
Green “24 V” LED dark	Card not powered (supply < 20 V DC, fuse open or polarity reversed)	Check cabinet PSU is 24 V DC ± 20 %, inspect DIN-rail fuse & wiring, then repower the card.
Green “15 V” LED dark while 24 V is OK	On-board logic regulator failed	Measure +15 V at monitor pin z22; if 0 V, replace regulator or the complete card.
Yellow “Drive-enable” LED remains off though PLC sends > +10 V to z24	Enable line < +6 V at pin z24 (broken field wire / PLC output)	Trace cable, restore > +10 V, reseat card to reset latch.
Red “Overload” LED lit	Solenoid current > 1.5 A (shorted coil or wrong valve)	Measure coil resistance, inspect cable for shorts; fit correct coil, the LED clears automatically.
Command signal present, no valve movement	PID enable switch D1-D9 off, or gain / set-min* pots fully CCW*	Verify DIL-switch positions (D1–D9) and turn gain / set-min clockwise until MP1 shows ≥ ±0.5 V.
Valve jerks, ramp pots ineffective	Ramp-bypass link b12–b20 left closed	Open the jumper or connect to remote switch to bring ramp generator back in circuit.
MP2 (LVDT feedback) ≠ command or red “LVDT fail” LED	Feedback cable open or wrong pinning (b14 / z22 / b16)	Check 6-pin LVDT connector, repair wiring, re-zero PID controller.
PID integrator saturates (MP6 pegged)	Incorrect I-gain or sensor polarity	Reduce I-gain pot, swap sensor wires, power-cycle to clear saturation.
Red “Sensor fail” LED	Feedback sensor out of range or 0 V	Verify sensor supply ±15 V on z22/z2/b2, replace faulty transducer.
Card resets when ambient > 50 °C	Internal over-temperature	Improve cabinet ventilation, keep card away from heat sources; allow cool-down before restart.

EEA-PAM-553-D-32	KSDG4V-3 servo spool	Strip-guidance / position PID with dual sensors	Quad-ramp (each quadrant)	Two LVDT fail LEDs, Overload, 24 V, 15 V	2

Indicator / Condition	What It Means
24 V LED off	No or low 24 V DC reaching the card
15 V LED off (24 V LED on)	On-board logic rail missing
Enable LED dark while PLC sends > 10 V	Drive-enable line actually < 6 V at pin z24
Overload LED lit	Coil current > 1.5 A (shorted coil or wrong valve)
Command present but no spool/pressure	Set-minimum or Gain* pots fully CCW*
Ramp pots ineffective / valve jerks	Ramp-bypass link b12–b20 left closed
LVDT-fail LED lit	Feedback sensor open-circuit or out of range
PID integrator saturated (MP6 pegged)	I-gain too high or sensor polarity wrong
Card resets below 19 V	Low-supply protection tripped
