Old FW-1000 Control Box Manual

The FW-1000 Control Box has been deprecated, and is no longer available.

The Shutter Control Panel shown in the photo below has been deprecated, and is no longer available.

The current filter wheel hardware options available are the Standalone FW-1000-SA unit and the TGFW card inside the TG-1000 Tiger Controller, see the FW-1000 Filter Wheel Manual.

The FW-1000 control box houses multiple control panel cards and allows for more than two wheels as well as future expansion. The Main Power Switch energizes the appropriate internal power supplies to energize the panels inserted into the unit. A FW-1000 system can be supplied with just a Filter Wheel Control Panel, or may have the optional Shutter Control Panel as seen in the photo above. Note: ASI no longer supports mechanical shutters.

One Filter Wheel Control Panel can handle two filter wheels and simultaneously move both wheels to the next set of filter positions. It may be controlled by the button or trigger input on the panel. A Shutter Control Panel can handle two shutters, including the optional built in shutters available with FW-1000 filter wheels. Both filter wheels and shutters may be controlled by computer commands via the RS-232 connector on the Filter Wheel Control Panel. The shutters may also be controlled via the switches or TTL trigger inputs on the Shutter Control panel.

AC Input:  90-264 VAC, 3.3 A (peak), 50/60 Hz
AC In-rush Current (Cold Start):  7 A (maximum), at 240 VAC

Fuse Replacement: 
2.0 A Fast Blow 250 VAC, 5x20mm H pack fuse - for 110-120 VAC Operation
1.6 A Fast Blow 250 VAC, 5x20mm H pack fuse - for 210-230 VAC Operation
3.3 A Fast Blow 250 VAC, 5x20mm H pack fuse - for 100-105 VAC Operation

PLEASE NOTE: ASI no longer supports shutters. The FW-1000 Shutter Control Panel is no longer available.

The FW-1000 Shutter Control Panel provides for control for two shutters, 0 and 1. The shutters are connected to the controller with the 0 and 1 6 Pin Mini Din Female Connectors on the front panel. Upon power up, any connected shutter will go to its default position of OPEN or CLOSED depending on the position of the shutter’s toggle switch and the type of shutter (normally open or normally closed). It should be noted that the panel/card will be set for either a normally open or a normally closed shutter at the factory. This setting can be changed using the Shutter Setup command (see page 35). The Shutter Control Panel is controlled internally through the Filter Wheel Control Panel’s RS-232 computer control serial port.

The two toggle switches for shutter 0 and 1 at the top of the panel allow manual override control of the shutter. When the toggle switch is placed in the left position, the shutter control is in the RS-232 controlled state that defaults to the de-energized position of the shutter at power up. When the toggle switch is moved to the right position, the control panel will energize the shutter for that switch. It should be noted that the switch must be in the LEFT position to be able to control the shutter through the Filter Wheel Control Panel’s RS-232 computer control port.

If the shutter has a built in internal position sensor, the corresponding LED will indicate the shutter is in its OPEN position if lit. If no internal position sensor is detected, the LED will always remain unlit.

A TTL input may be connected to the TRIG IN BNC Connector for external control of each shutter. A +5vdc signal applied to the internal pin of the TRG IN BNC connector (the outer connector is ground) will override any computer controls and energize the shutter.

Whether it be computer serial control, toggle switch control, or TRG TTL control of a shutter, an energize signal from any one of them will dominate, and that shutter will remain energized until all control sources return to their de-energized state.

Plug the AC power cord into the rear of the controller. Attach the cable between the filter wheel and the controller. Connect the serial cable between the computer and controller.

On filter wheel jumper JP4, connect 1-2 and 3-4.
On the shutter card jumper J1, connect 1-2, 3-4, and 5-6.

The following commands are used to control shutters with an SH 2 controller in the same cabinet as the FW-1000 controller. The parameter n may have any value from zero to (2N 1), where N is the number of shutter controller cards in use.

Syntax: SO n
Opens shutter number n.

Syntax: SC n
Closes shutter number n.

Syntax: SQ [n]
Returns a decimal status byte from a shutter control register. The n parameter is optional in the Shutter Query command. If no n is specified, then the command returns the status byte from the most recently used shutter controller. If no shutter commands have been issued since the last system startup, then the command returns the status byte from the controller of shutters 0 and 1. If no SH 2 Card is present, 0 is returned.

In the descriptions of Bit 0 and Bit 1 below, an energized, normally open shutter is closed; a de-energized, normally open shutter is open; an energized, normally closed shutter is open; and a de-energized normally closed shutter is closed. In other words, a de-energized shutter is always in its normal state. The binary equivalent can be decoded as follows:

Syntax: SS x
Supports shutter control. Normally, the SC command causes the controller to energize a shutter, and SO causes the controller to de energize it. Most shutters are normally open; i.e., open, unless energized by the controller via the SC command. The SS parameter x is a binary number representing eight bit positions, i.e., an integer in the range 0…255. Within x, if some bitk is set, then shutter k is normally closed. With this setting in effect, the effects of SO and SC are reversed. Instead of SC causing the controller to energize the shutter, SO energizes it, and vice-versa. Once determined, this value may be saved to non-volatile (flash) memory using the RS command.

The default value of x is zero, denoting that all shutters are normally open.

Examples: SS 2 is correct if Shutter 1 is normally closed, because x has Bit 1 set. SS 3 is correct if shutters 0 and 1 are normally closed, because x has Bits 0 and 1 set.

Cleaning should be done with a 70% isopropyl alcohol solution. Maintenance should only be done by ASI, or an ASI approved technician - no user serviceable parts inside.
