VED24 User Manual 25
Trigger Cautions and Trouble Shooting Tips
1. The VED24 system's capability is greatly enhanced by external control as described
previously, however, extreme care must be taken to ensure that high voltages (see
SPECIFICATIONS) are not inadvertently switched into external control inputs. Also, note
that large negative voltages can cause irreparable damage to the unit's internal circuitry.
Exercise extreme caution.
2. Fuses are located internally on the PCB. If a fuse is inadvertently blown, it is not
recommended that the user change a fuse.
3. Particular shutter units respond to different minimum pulse widths. For example, a standard
DSS35B shutter (equipped with Teflon blades) has a minimum exposure pulse of 45 msec. If
the exposure or pulse width presented to the
VED24 ’s PULSE INPUT is less than 45 msec,
the shutter may not open fully. If the unit still does not operate properly, when the proper
pulse width is presented to the PULSE INPUT, please notify Vincent Associates
immediately.
4. Please be sure that FUNCTION switches are set correctly before operating the shutter.
Incorrect switch settings can damage the shutter and/or trip the internal fuses. Additionally,
this could result in the shutter not opening fully when triggered or opening fully and
immediately returning to the closed position thereby risking failure or loss of capture.
5. Unless otherwise indicated, based on the shutter used with the VED24 , be sure that
FUNCTION switch #2 is in the “up” position. This setting ensures the internal shutter driver
voltage is set to +10.7VDC. The “lower” FUNCTION switch #2 position sets the internal
shutter drive voltage to +18VDC. This should only be set to this position when the shutter
used indicates this setting should be made. Use of this voltage setting for smaller aperture
devices could cause irreparable damage to the shutter used and WILL void the shutter’s
limited warranty.
