NL 200 Series Controller User Manual 3 1 E 4 Mounting In order to provide fixing points to mount the unit onto a flat surface or bracket M3 nuts must be inserted into one or more of the slots in the base see illustration below The quantitv and position of these nuts is dependant upon the users requirements To fit a nut remove one of the end covers The nuts can then be slid into the slots and the cover replaced Ensure that the fixing screws used do not extend past the lower base surface by more than 5 5mm See Addendum for installation of optional DIN Rail Mounting Kit 4 1 Environmental considerations The NL 2XX enclosure is a fire enclosure as long as it is mounted so that none of the connectors are facing downwards If a fire enclosure is used the enclosure should be metal or plastic with a flammability rating of UL94 V1 or better with no holes below or to the sides of the NL 2XX when mounted Cable entries below the NL 2XX should be via glands that have a flammability rating as before The NL 2XX should be at least 10mm from any other part or side of the enclosure The NL 2XX does not have an IP rating and should be mounted so that moisture and dirt cannot enter the unit b a DIN934 BS3692 1SO4032 SHOWN 106 5 O ie NL 200 Series Controller User Manual 4 1 E 5 Connections See the Specification Appendix A for information on connection ratings 5 1 Power Su2. 001 and then will be ready a Fa Set up an for operation To show that the unit is operating normally an 4 enoar alternating pattern is drawn on the display Once a light is CH2 ps connected the controller will sense it as described below in UP DOWN Lighting Setup Me Set ba li LOC key lock Note if light s are connected and have no rating specified me ae for them then an error is indicated To set the rating refer to section 7 1 ae The overall structure of configuration is given to the right ai ti disks To configure the controller from the keypad press and hold trg ps pce SEL for 1 second CH1 will be displayed Use UP and ir taa DOWN to select which feature to set up SEL be Pressing and holding MODE at any time will cancel the veroon ara operation m kie mi alla Using the kevpad it is possible to set the configuration for each channel set a kevlock code so that unauthorised users cannot change anv settings set the internal trigger timer view trigger status and set the voltage or current rat ing of each of the channels 8 2 Setting the Lighting Rating This is described in Lighting Setup Section 7 NL 200 Series Controller User Manual 8 1 Front Panel Configuration NL 200 NL 220 NL 220F 8 3 Default Displav When the NL 2XX is not being configured the displav shows the status of all the channels The seg ments and their meanings are given below These segments are on when a light is

4. Any triggers that happen too soon after the previous trigger are ignored The retrigger delay is set in multiples of 100us In pulsed mode the brightness can be set up to 1000 of its rating but only for short periods and at low duty cycles so that the lighting does not overheat and get damaged The duty cycle is limited by ignoring triggers which are too soon after the previous trigger Output Brightness Allowed Pulse Width Allowed Duty Cycle 501 to 1000 So for example if the brightness is set to 250 then the NL 2XX will not allow pulses greater than 10ms long With 10ms pulses if a trigger occurs within 50ms of a previous trigger so that the duty cycle would be greater than 20 the trigger is ignored If necessary the NL 2XX will limit the duty cycle by increasing the retrigger delay WARNING To prevent possible overcurrent condition when operating NERLITE Strobe models initiate the brightness setting to 10 then increase current appropriately 6 1 3 Fault Detection The NL 2XX detects the following errors When the output current is less than 100mA some fault detection is turned off Internal power dissipation is too high Output turned off Output current to lighting is too low The light is open circuit or there is not enough supply voltage for the requested output current The voltage required for the lighting has increased too much Check for ageing of the lighting or a failed LED The voltage required for the
