OPERATING MODES
Plug n’ Go
The LMLS-500, unlike most other DLM Components, will not auto-configure. The LMLS-500 must be manually configured using the
LMCT-100 or LMCS-100.
Push n’ Learn
Push and Learn™ (PnL) provides for remote load binding and configuration within the room, without requiring direct access to the Room
Controller(s). While the
LMLS-500 must be configured through the use of a configuration tool (e.g., LMCT-100), the CONFIG button at the back of the product
can be used to force the system into or out of PnL, and/or to step to the next load in sequence.
Confirmation of Load Binding
To provide a confirmation of load bindings after installation, a quick press using a paper clip on the USER button sequences through
three states:
1st press - all controlled loads forced ON at 100%
2nd press - all controlled loads forced OFF at 0%
3rd press - exit load binding confirmation mode and resume normal control. (Confirmation mode cancels automatically after 5 minutes if
no further action is taken after the 1st or 2nd press.)
Test Mode
In Test Mode, time delays are reduced to 5 seconds (to create near-immediate reactions to changes in measured light levels), and the
ramp rate increases to 20%/second (to cause the changes to be immediately visible).
To activate Test Mode, press and hold the USER button for 2 seconds or use a configuration tool. If not cancelled by the user, the
controller automatically exits Test Mode after 5 minutes.
User Override of Levels Set by Daylighting Control
The electric light levels of loads configured for daylighting control can be adjusted from DLM wall switches, within limitations established
by LMLS parameters that are set using the Advanced Settings screen of the LMCT-100.
The light level can always be reduced (by turning off loads in a switched zone, or by lowering the level of loads in a dimmed zone)
without restriction. When a load is dimmed down from its daylighting-permitted level, the new level set becomes the maximum electric
light level for that load (a “cap” level), regardless of daylight contribution, until the load is turned off and back on again, or until the
level is adjusted upwards. If a load has been dimmed, a single tap on the top of a controlling switch’s rocker will return the level to the
maximum allowed by daylighting at that time, and cancel the level restriction (“cap”) set by the earlier user adjustment.
Increasing the light level above that set by daylighting is possible only if
Allow Override
is set to
Yes
(the default is
No
). For switched
modes, this means that the loads can be turned on even when the present ambient light level is above the On Setpoint. In the case of
dimmed mode, a load will turn on and adjust to its daylighting-permitted level, but a subsequent tap on the top of a controlling switch will
increase the level to maximum. In either mode, the affected loads will be temporarily removed from daylighting control, and be placed in
an “override” state. The levels of the overridden loads can be changed or adjusted, and they will not return to daylighting control unless
they are turned off and back on again (for example, by a cycle of occupancy).
If the
Override Time parameter is changed from its default ( Infinity ) to a fixed time (e.g., 1 hour), all loads presently overridden will
return to automatic daylighting control after the selected time period lapses.
Any loads not affected by the switch actions causing the override will continue to be controlled by daylighting; overrides occur on a load-
by-load basis.
If any daylighting loads are presently overridden, the blue LED in the sensor head will flash once every four seconds.
To provide the ability to set arbitrary light levels in Dimmed applications, a switch with a dimming control rocker (e.g., LMDM-101 or
LMSW-105) should be used.
Scene Control and Daylighting
Setting a new light level using a scene switch is possible, provided Hold Off is set to No (default). Such a light level change is not
considered an override. If daylighting control is active when the new scene is selected, daylighting control suspends until the new scene
is displayed, and then resumes, with the new light level established by the scene as the maximum electric light level (“cap” level), on
a load-by-load basis, until a subsequent user action changes the level. Any daylighting loads not included in the scene will continue to
operate as before the recall.
Optionally, daylighting control can be temporarily disabled for any loads on which a scene has been recalled. If
Scenes Stop DL is set
to Yes , daylighting control for a load affected by a scene will not resume until the level of the load is changed by another user action, or
the load is turned off and on again.
