5 Operation
5.3 Time Programming and Mode Selection
The following steps are necessary to set up a cure time and change to time controlled
mode:
● Press the trigger button in a fast sequence of four times.
The device beeps, once per second to show that it is expecting a time to be
programmed. The new exposure time shall now be programmed within 10 seconds.
If the UV light (and the yellow LED) should already be active due to an external start
signal or due to the timer already running, UV curing will be interrupted.
● The trigger button is pressed and held, as long as the desired exposure time shall be.
During programming the unit continues to beep every second, that sound may be used
to estimate the duration by counting the beeps. After the trigger button is released, the
set exposure time is stored and the time-controlled mode is automatically entered.
Starting a time controlled exposure is possible by:
–pressing the trigger button
1
or
–applying an external start signal (voltage pulse) from a higher-level controller
Note!
The cure time may be adjusted from 0.5 to 120.0 seconds with a resolution of 0.1
seconds.
How to change back to continuous operation mode:
● Press the trigger button shortly in a sequence of four times and then wait 10 seconds,
until the unit stops beeping, without pressing the trigger
button.
6 Maintenance and Service
The EQ CL32 LED Spot is generally maintenance-free. Please avoid fingerprints on the
glass surfaces!
Caution!
Vapours from some products may gradually accumulate on the optical lens of the device,
reducing the light output. It should be inspected regularly and cleaned as necessary
using isopropyl alcohol and a soft, clean cloth.
The light output
3
of the EQ CL32 LED Spot should be monitored periodically using a
radiometer as various factors may influence the optical output power.
Use the Radiometer Dosimeter
UV LED, UVA and UVB (for 365 nm)
, order no. 1390323
or
Visible LED, UVV (for 405 nm)
, order no. 1265282 to monitor the optical output.
To monitor the UV performance follow the steps in the instruction sheet of the
radiometer. Irradiate the sensor by manually pressing the trigger button
1
or by using the
control interface
6
of the EQ CL32 LED Spot.
An adaptor is available to accurately position the EQ CL32 to the radiometer back.This
provides consistant position and distance for maximum repeatability of the
measurements. See next section for ordering informations.
