OUNTING AND OPERATING THE

BARNDOOR UNIT

The barndoor unit is designed to be mounted on a MAC 2000 Wash fixture.

Before starting

The electric connection socket for the barndoor accessory was reversed on some MAC 2000 Washes
before S/N 4001816001 (you can find the serial number of your MAC 2000 Wash on the serial number label
underneath the base). Although the socket is coded, the barn door plug can be forced in backwards.
Damage to the electronics will occur if power is applied with the connection reversed.

To avoid damaging the barndoor´s electronics, check the socket´s orientation before installing and operating
the barndoors. The orientation can be checked by examining the triangles in the middle of the socket. When
installed correctly, the tips of the triangles point IN towards the lens as shown here.

If the triangles point away from the lens, you can contact your Martin Dealer and have them perform the
modification, or you can do it yourself:

1 Lock the head in the horizontal position with the top-side up.

2 Remove the left-front head side cover.

3 Loosen, but do not remove, the top screw for the connection socket.

4 Remove the bottom screw.

5 Work the socket free and turn it 180 degrees.

6 Place the u-shaped bracket on the bottom of the socket.

7 Position the socket in the top u-bracket and fasten.

8 Verify that the socket is squarely aligned and the triangles point in.

9 Replace the head side cover.

Mounting and operating the barndoor unit 5

Mounting the barndoors

Warning For safety reasons we do not recommend that this procedure be performed while the

fixture is rigged.

1 Referring to the instructions in the MAC 2000 Wash user manual (P/N 35000114), set the personality

settings on the MAC 2000 Wash to match the lens that is installed in the barndoor unit. If the PC lens is
installed then use the control panel to set PERS>bdL>PC L. For all other lens, including the standard
diffuser lens, use the default setting, PERS>bdL>dF L.

2 Disconnect the MAC 2000 Wash fixture from power.

3 Lock the fixture head in the “top” horizontal position.

4 If present, remove the lens that is installed on the MAC 2000 Wash by unscrewing the four quarter-turn

screws, pulling the lens housing away from the fixture, and releasing the safety cable.

5 Attach the barndoor safety cable to the MAC 2000 Wash and lock it in place using the thumb-screw. Ensure

that the cable slack is kept away from the optical path.

6 Push the barndoor unit into place so that the interface connector on the rotation assembly (at the rear of the

barndoor unit) connects correctly to its counterpart on the MAC 2000 Wash. Ensure that the cable slack is
taken up outside of the barndoor unit.

7 Hook the fold of safety-wire slack under the lip of the MAC 2000 Wash head cover as shown in the following

illustration.

8 Rotate the barndoor unit to the upright neutral position.
