Figure 2- Ultracure 7 LED unit dimensions and mounting.
Mounting
The Ultracure 7 has three mounting options on the LED unit: Four M4 x 0.8 on electrical connector end,
two M4 x 0.8 on the bottom face of the device, and two M4 x 0.8 on both sides of the LED. Refer to
Figure 2.
The control box has two M3 thru-holes for mounting. A DIN Rail adapter, or “Dinclip”, can be used, and
is included along with required mounting screws. The control box must be opened in order to install the
DIN Rail adapter.

Operation Guidelines
Wiring Configurations
The Ultracure 7 can be wired with or without status feedback.
Quick Install –No Feedback
Connect 24VDC as shown for quick install with no feedback.
Figure 5 - Ultracure 7 pin connectors, with pins labelled. Shown wired in no-feedback configuration.
Single Unit Wiring with Feedback Status I/O
Reference Drawing on next page.
The Ultracure 7 unit will turn on under the following conditions: when the Power Supply (PS1) is on, the
Switch (SW1) is closed, and shutter relay contacts are open.
If the unit has an over temperature error or a burned out LED, the error relay will turn on, opening up
the NC contacts.

Figure 6- Single-Unit Wiring.
The Ultracure 7 unit will turn on/off quickly when the shutter relay contacts are opened/closed. If the
shutter relay is not used, leave Pin 3 disconnected and the unit will turn on and off with SW1 only. The
cooling fans will be turned off with SW1 as well. DO NOT connect Pin 3 to anything over than 24
RETURN! Status Relay Contacts in each unit are rated for 30VDC and 2A.
Multi-Unit Wiring with Feedback Status I/O
Reference Drawing on next page.
When PS1 is on, switch SW1 is closed and shutter relay contacts are open then all the Ultracure 7 units
in the Multiunit loop will turn on. The green LED on each unit will turn on when the units are on. If one
of the units has an over temperature error or a burned out LED then that units’ error relay will turn on
and the error loop will open. The red LED will turn on when an error is active. The Ultracure 7 units will
turn on/off quickly when the shutter relay contacts are opened/closed. If the shutter relay is not
used/required then leave Pin 3 disconnected and the units will turn on/off with SW1 only. The cooling
fans will be turned off with the SW1 as well. DO NOT connect Pin 3 to anything other than 24 RTN of
this multi-unit loop! Status Relay contacts in each unit are rated for 30VDC and 2A.

System Status/Faults
Two status indicator LED’s are located on top of the
module.
Green lamp: Power on and working properly.
Red lamp: Indicates one of the following Fault Conditions:
LED failure open
LED short
Pink lamp: Over temperature
If the fan fails, or the ambient temperature gets too
high, an automatic shutdown will protect the LEDs. The
LEDs are forced off if the unit temperature reaches 60°C,
and will stay off until the substrate cools down to 55°c.
UV Output Curve
The Ultracure 7 has an optimal distance for ideal curing properties. The diagram below shows the UV
Intensity vs Distance Curve.

External I/O Signals
The only output signal on the Ultracure 7 is an Error signal from port 2. Refer to Figure 5
LED Failure
The unit has experienced an LED failure; this is fixed by opening the driver enclosure and flipping
the corresponding dipswitches one at a time (from 1 to 5) until the unit turns back on. The unit
will operate properly with one or more inoperable LEDs.
Dip s/w 6 allows customer to bypass the closed led fault condition. (Note: red fault lamp will
stay illuminated). Once bypassed customer must manually inspect for led failures.
Maintenance
Verify the protective glass is clean.
Frequently Asked Questions
Q: Why is my unit turning off by itself?
A: LED failure, refer to next question for answer.
Q: The unit no longer turns on, but the unit is not hot what happened?
A: The unit has experienced an LED failure; this is fixed by opening the driver enclosure and flipping the
corresponding dipswitches one at a time (from 1 to 5) until the unit turns back on. The unit will operate
properly with one or more inoperable LEDs.
