4.8.2 Slidewire Emulation
The Slidewire Emulation Output Card (51404886-003) can be calibrated for Slidewire Supply voltages
between 1.0 Vdc and 20 Vdc. The Actuator leaves the factory with no Slidewire Supply connected to the
terminals.
To calibrate the Slidewire Emulation output:
1. Remove power from the actuator, and connect the Slidewire Supply between the “H” and “L”
terminals on the terminal plate. (Terminal 34 for the “L”, the low voltage side of the source and
terminal 36 for the “H”, the high voltage side.) See Figure 3-11.
2. Connect a precision voltmeter, + and – leads, to terminals 35 and 34 on the terminal plate.
3. Apply the AC power to the actuator. Apply power from the Slidewire Source.
4. If actuator is set for CW operation, switch it to CCW operation. See Section 4.9, Step 1.
5. Position the actuator to the 25 % position on the CCW scale. (75 % position on CW scale.)
6. Read the voltage on the DVM. The reading should be 25 % of the Slidewire Supply
±
0.75 % of span.
7. If the reading is incorrect, adjust R5 until the reading is within tolerance.
8. Position the actuator to the 75 % position on the CCW scale. (25 % position on the CW scale.)
9. Read the voltage on the DVM. The reading should be 75 % of the Slidewire Supply,
±
0.75 % of span.
10. If the reading is incorrect adjust R59 until the reading comes into line.
11. Repeat steps 4 through 9 until the readings are within tolerance.
12. If CW operation is desired, switch actuator back to CW operation by following Section 4.9.
