(6) Insulation Test 
CAUTION: BEFORE YOU DO THE INSULATION TEST, MAKE SURE THAT THE ACTUATOR IS NOT CONNECTED TO THE ELECTRICAL TEST-UP. 
(a) For Versions ABCDE 
ACTION  RESULT
1  Make sure that pin M of the connector is connected to the casing of the actuator. 
2  Connect pins H, J, K, L, N, R and V together. 
3  Connect pins G, P, S, A, B, C, D, E, F ,T and U together and to the Ground. 
4  Apply 500 VDC between pins [ H, J, K, L, N, R and V together ] and pins [ G, P, S, A, B, C, D, E, F ,T and U together ] during 1 mn. 
5  Disconnect all wires. 
6  Connect pins A, B, C, D, E, F ,T and U together. 
7  Connect pins G, P, S, H, J, K, L, N, R and V together to pin M and to the Ground. 
8  Apply 45 VDC voltage between pins [ A, B, C, D, E, F ,T and U together ] and pins [ G, P, S, H, J, K, L, N, R and V together to pin M and to the ground] during 1 mn. 
Make sure that insulation resistance is more than 100 M..

(1)  Strokes, Microswitches and Potentiometer Test 
(a)  For Versions ABC 
ACTION  RESULT
1  Remove the protective sleeve or the protective jacket from the ball-screw. 
2  Connect the actuator to the Electrical Test Set-Up (ratiometers) (Ref. to Fig. 1001). 
3  Carefully set the auto-transformer to have a very low displacement speed (lower than 1 mm/s (0.039 in/s)). 
4  Set the actuator to the MECHANICAL STOP EXTENDED position (door fully closed) (Ref. to Fig. 1002). 
5  (Ref. to Fig. 1005). 
6  Measure the distance DRF between the measurement point X and the measurement point Y. 
7  Measure the total resistance X of the main potentiometer between pin A and pin C of the connector. 
8  Measure the total resistance Y of the secondary potentiometer between pin D and pin F of the connector. 
9  Calculate |X – Y|. 
10 Measure, with the ratiometers, the voltage ratio AB/AC between pin A and pin B and between pin A and pin C (AC). 
Record DRF. 
Make sure that X = 6600 ± 660 .. Record X. 
Make sure that Y = 6600 ± 660 .. Record Y. 
Make sure that |X – Y| < 660 .. Record |X – Y|. 
Make sure that AB/AC = 0.9273 + 0/- 0.0080. 
Record AB/AC.

ACTION RESULT
11 Measure, with the ratiometers, the voltage ratio DE/DF between pin D and pin E and between pin D and pin 
F. 
12 Carefully set the auto-transformer to have a displacement speed between 3 mm/s and 5 mm/s (between 0.118 in/s and 0.197 in/s). 
13 Set the actuator to the ELECTRICAL RETRACTED position (door flight opened). 
14 Measure the distance D between the measurement point X and the measurement point Y. 
15 Measure, with the ratiometers, the voltage ratio AB/AC between pin A and pin B and between pin A and pin C (AC). 
16 Measure, with the ratiometers, the voltage ratio DE/DF between pin D and pin E and between pin D and pin 
F.
