to be defective excepting transportation charges. Burned out or otherwise damaged actuator coils are not covered under this warranty. Any
defective product returned to the MANUFACTURER must follow the RETURN MATERIAL AUTHORIZATION PROCEDURE as
defined below. This warranty does not extend to cover damage resulting from alteration, misuse, negligence, abuse, normal wear and tear,
or accident. The MANUFACTURER will consider the return of unused equipment if returned within 30 days from the original date of
shipment, subject to a 20% restocking charge. This offer does not apply to used or damaged equipment. This warranty extends only to the
original purchase and is not available to any third party, including any purchaser assemblies or other Products of which the goods may
become component equipment.
CYCLE WARRANTY CRITERION: One “cycle” is considered one open and one closure of the shutter. DSS Shutter must be operated
with the ED12DSS driver or equivalent H-Bridge type shutter driver circuit at +10.7VDC across the actuator coil for the specified duration.
DSS Shutter must be operated within the defined environmental, electrical and mechanical specifications as listed on the device’s data
sheet. After one year (WARRANTY PERIOD), the cycle warranty is null and void. If returned, the device must be accompanied by a
written statement indicating the approximate number of cycles contained on the device, include all parameters to which the shutter was
operated and follow the RETURN MATERIAL AUTHORIZATION PROCEDURE as defined below.
RETURN MATERIAL AUTHORIZATION PROCEDURE: MANUFACTURER will only accept returned Products from customers
that have obtained an RMA (Return Material Authorization) number from the MANUFACTURER. The customer must also include an
itemized statement of defect(s). The Product will then be evaluated per the MANUFACTURER’S standard repair guidelines. Any Product
which has been returned to the MANUFACTURER but which is found to meet the applicable specifications and not defective in materials
and workmanship shall be subject to the MANUFACTURER’s standard evaluation charge. The MANUFACTURER assumes no liability
for customer returned material.
LIMIT OF LIABILITY: The buyer's exclusive remedy and the limit of MANUFACTURER'S liability for any loss whatsoever shall not
exceed the purchase price paid by the buyer for the goods to which a claim is made. MANUFACTURER does not give any implied

INTRODUCTION
The ED12DSS is the optimal driver for the new UNIBLITZ® N-CAS® DSS Shutter Series. This
device will operate a single DSS shutter or a single NS series bi-stable shutter from a +12 to 24VDC
power supply. (Bi-stable mode only requires power when switching the shutter’s state.) Once the input
and output connector harnesses are connected, the user selects the open and close pulse duration - via the
on-board 4-position piano switch - and connects a user supplied power supply. Once the shutter and the
TTL input signal are connected together, the shutter’s exposure can be controlled via a TTL square pulse
input. (Pulse duration determined exposure time.)
The ED12DSS can be easily integrated into OEM applications where a +12 to 24VDC power supply is
available.

OPERATING INSTRUCTIONS
OPERATION
***Please observe anti-static unpacking procedure when removing the ED12DSS from the static
shielding bag. Improper handling can result in destruction of the integrated circuits located on
the board surface.***
The ED12DSS provides the circuitry necessary to efficiently drive DSS shutter units. By providing the
unit with the necessary initiating control signal, the shutter can be made to open and close on command.
The on-board microprocessor accepts a pulse width determined exposure time and produces the bi-stable
open and close pulse whose duration is selected by the on-board piano switch, S1.
Prior to the connection of input/output signals to the ED12DSS be sure the 5-pin connector of the EDIOP (power/trigger input connector) is disconnected from the 5-pin post connector, P1 and that your
power supply is in the off position. Set S1 to the pulse duration required for the shutter you will be
using. See SPECIFCATIONS and/or Figure #2 for required settings.
Connect the Red wire of the ED-IOP harness to the (+) side of a +12VDC to +24VDC 1.5A power
supply and the Black wire of the harness to the (-) return side of the power supply. Connect the 5-pin
Female connector of the ED-IOP onto P1. (The connector is polarized and should only be able to
connect in one direction.)
Then connect the 203D shutter interconnect cable between the 2-pin P2 connector on the ED12DSS to
the 2-pin connector on the shutter’s flex interconnect. You can now turn on your power supply.
Connect your input signal, active high TTL to the input BNC. Once the ED12DSS receives an input
signal the shutter should open at rising edge of the input pulse and close at the falling edge of the input
pulse. See Figure #1.
If you need to operate the shutter from a switch contact closure, you will need to connect a wire to pin
#5 of the ED-IOP harness. This is the +5VDC output. If you then switch the +5VDC into the BNC
input, the shutter will open and remain open for as long as the switch contact is depressed. Once the
+5VDC is removed from the input, the shutter will return to the close position. See Figure #1.
Reference drawings #16-0622 (Figure #1) for input signal types and #16-0618 (Figure #2) for proper
input/output connections to the ED12DSS.
***CAUTION, failure to connect the power supply properly will result in extensive damage to the
drive unit and/or power supply.***
FUSE REPLACEMENT
F1 is a 0.25A fast acting SMT fuse that is soldered to the ED12DSS. This fuse is non-replaceable. F2 is
an SMT replaceable fuse. This fuse can be removed and replaced in the field. Follow standard antistatic procedures when replacing this device. Fuses can be procured from the manufacturer.

MISCELLANEOUS
The repeat exposure specification of the ED12DSS listed in this manual is limited by the type of shutter
used and the open/close pulse duration selected by S1. (See SPECIFICATIONS, GENERAL
CHARACTERISTICS S1 Settings Chart.) At higher frequencies heat could begin to rise in the shutter
coil especially if the shutter is enclosed in an area of limited air flow. This heat in the shutter coil could
cause premature failure. Please contact the factory for specific information concerning shutter
modifications and/or drive modifications that may be necessary for operating shutters at their maximum
frequency. Please also note that the shutter output is fuse protected.
***Under certain circumstances multiple ED12DSS drive units can be operated from one power
supply. If your requirements do not necessitate shutters to open at the same instance, two drivers
may be operated from one supply. It would be advisable to discuss your particular application
with one of our customer service representatives.***
MAINTENANCE
Although the stability of the drive voltage and timing of the on board microprocessor is assured and
calibrated prior to shipment, it may become necessary to make some minor adjustments to the circuit of
the ED12DSS over time.
It is highly recommended that if you suspect a problem with your unit that it is returned to the factory
for proper adjustments and calibration. The unit's circuitry may be damaged and/or not function as
specified if adjusted improperly.
Proper care and maintenance of the unit should be taken as with any electronic instrument. This device
is for indoor use only.
