Assembly

Requires tools (#2 Phillips head screwdriver, Allenwrench and Torque wrench for screws), Scotchbriteor equivalent abrasive, a mild solvent to clean surfacesand Electrolube 2 GX or equivalent thermal grease.

The mounting surface of the heatsink must be flatand clean (i.e., bare metal) and the SCR surface mustbe clean. Thermal compound must be coated on allmating surfaces between the SCR package and theheatsink. Care must be taken to use the specifiedtorque for mounting the SCR package.Step 21. For SCR module mounting, clean the heatsinksurface with a fine abrasive such as Scotchbrite,remove all particles from the surface of the heatsinkand wipe the SCR mounting surface with a mildsolvent. Apply a light coat of thermal compound suchas Electrolube 2 GX to both the SCR and heatsinksurfaces. Place the contact face of the SCR package onthe mating heatsink surface and move the SCRpackage back and forth several times to distribute thethermal compound evenly over the contact surfaces.

Step 22. Use the screws provided to attach the SCRpackage to the heatsink. Tighten the screwsalternately to the specified torquerequirement for the SCR package.

Torque requirements are as follows: Tightenthe screws through the SCR package toheatsink— 44 in lb.

Step 31. With the (2) SCRs located properly on theheatsink, i.e. the gate and cathode terminalson the SCRs must be on the proper side ofthe heatsink assembly (as disassembled),place the other heatsink over the SCRs. Refer to Figure 13.

The clamp is assembled so that the crosspiece (5) with the pressure plate (4) and thetension bolts (10) are at the top. Underneath,the cross piece (3) with the pressure plate (4)is put in position and the two tension bolts(10) are alternately tightened carefully until aslight resistance is felt. Check that both crosspieces (3) and (5) are parallel. For this check,it is sufficient to check that the tension boltsproject equal distances beyond the crosspiece (3). The tension bolts (10) may now bealternately tightened 1/4 turn at a time untilthe metal gauge (8) can be easily moved.

Note - The tension bolts should not betightened beyond the point that the metalgauge (8) can be easily moved. Never adjustor change the position of the preset nut (6).The preset nut (6) determines the clampingforce applied to the SCR.

Step 18. Label the 6 push-on wire connectors with thenumbers printed on the P.C. Board (U1, V1,W1, U2, V2, W2). Remove 6 push-on wireconnectors from the Protection Board(Figure 9). Note the location of theseterminals for reassembly.

Step 19. Label the 4 leads from the two currenttransformers and the 2 leads from thethermostats to assure connections are thesame to the 6-point Terminal Board on thenew Protection Board. Disconnect the 4 leadsfrom the two current transformers and the 2leads from the thermostats to the 6-pointTerminal Board (Figure 8).

Step 20. Loosen the mounting screws holding theProtection Board to the housing. Remove theProtection Board from the ASTAT-CD Plus.

Reassembly

Step 21. Reassemble the new Protection Board, thepush-on wire connectors, the CT leads,thermostat leads, screws, gate wires andground wire (if used), Logic and PowerSupply Board assembly, screws and ribbonconnectors in the reverse order of the abovelisted disassembly (Steps 16-20).

Step 22. Reassemble the plastic cover, connectors andsheet metal cover using steps 8-10.

To replace SCRs


Step 23. Remove the front cover by removing the (4)Phillips head screws (Figure 1).

Step 24. Phase 1 or 3 - Remove bus bars, the fanassembly, the top ventilating cover and theheat sink insulator cover. Remove thethermostat wires, gate and cathode leads fromthe SCRs, current transformer leads from theC. T. (only on Phase 1) and other parts thatinterfere with removal of the SCR/heatsinkassembly (Figure 10).

Phase 2 - Remove bus bars, the fan assembly,the top ventilating cover and the heat sink

insulator covers from both phase 1 and Phase3 heatsink assemblies. Remove (4) Allenscrews in the black plastic bottom housingthat holds the Control assembly to theheatsink assembly and move the assembly tothe side. Remove the thermostat wires, gateand cathode leads from the SCRs, currenttransformer leads from the C. T.’s, and otherparts that interfere with removal of theSCR/heatsink assembly (Figure 10).

CAUTION: Do not adjust or move the preset nut(6) (Figure 13). The preset nut (6) and the bevelwashers under the cross piece (5) are preset to therequired force for assembly and clamping of thenew SCR to the heatsink.

Step 27. Removing the SCRs (Figure 13) - Loosen thetension bolts (10) alternately, 1/4 turn at atime, on each SCR until pressure releases onthe SCRs. Remove bolts and clamps to releasethe heatsinks. Note: record the position ofboth SCRs (gate and cathode connectors onthe SCR) for reassembly.

Caution: Do not adjust or move the pre-set nut (6)(Figure 13). The pre-set nut and the bevel washersunder the cross piece (5) are pre-set to the requiredforce for assembly and clamping of the new SCR tothe heatsink.



Step 28. Clean both heat sink surfaces with a fineabrasive such as Scotch brite, then remove allparticles from the surface of the heatsinks. Toclean the SCR, wipe the SCR with a mildsolvent.

Step 29. Apply a light coat of thermal compound suchas Electrolube 2GX to both sides of the SCRand to both heatsink surfaces that mate to theSCR.

Step 30. Make sure that the orientation of the SCR iscorrect(as disassembled) and place thecontact face of the SCR over the locating pinin the mating heatsink surface. Twist the SCR

Step 31. With the 2 SCRs located properly on theheatsink, i.e. the gate and cathode terminalson the SCR must be on the proper side of theheatsink assembly (as disassembled), placethe other heatsink over the SCRs. Refer toFigure 13.

The clamp is assembled so that the crosspiece(5) with the pressure plate(4) and thetension bolts (10) are at the top. Underneaththe cross piece (3) with the pressure plate (4)is put in position and the two tension bolts(10) are alternately tightened carefully until aslight resistance is felt. Check that both crosspieces (3) and (5) are parallel. For this check,it is sufficient to check that the tension boltsproject equal distances beyond the crosspiece(3). The tension bolts (10) may now bealternately tightened 1/4 turn at time untilthe metal gauge (8) can be easily moved.

NOTE: The tension bolts should not betightened beyond the point that the metalgauge (8) can be easily moved. Never adjustthe preset nut (6).
