Description of Features
Refer to the sheet MH-3000 Settings in the schematic to see the settings and features
provided for each particular job. Some features may be incorporated into the Bit Features
that are listed under the Settings heading. The features that are most likely to require
changing are included in the Features heading. The following features are standard (All
features are normally off/disabled, unless otherwise specified):
•
No Shortened Door Time
- (Display shows "NO SHORTDOORTIME") Normally the
door time will be shortened by the Door Open Button/Safety Edge/Electric Eye/Infra-red
Curtain. Enable this feature to prevent these devices from shortening the door time.
This is normally required in nursing homes, where the passengers need more time to
enter the car. The Door Close Button will still shorten the door time.
•
Timed Electric Eye Cutout
- (Display shows "TIMED EYE CUTOUT") Enable this
feature to allow the Electric Eye input to be disabled after the preset time (see the
setting above for the delay before cutting out the Electric Eye). This feature is often
provided in the Electric Eye unit itself.
•
Door Nudging
- (Display shows "DOOR NUDGING") Enable this feature to activate
door close nudging. Nudging will be initiated if a call is registered and the doors have
been prevented from closing for the preset Door Nudging time. The Electric Eye will be
disabled, the Nudging Buzzer will come on, and the Nudging Output will come on if the
Electric Eye input is energized. This means the door will only close at slow speed if the
Electric Eye is blocked.
NOTE: Door Nudging operation requires an optional Nudging Buzzer output
and Reduced Speed Door Closing output.
•
One Stroke Down Lanterns
- (Display shows "1 STROKE DN LANT") The lanterns are
normally provided with two strokes for the down direction. Enable this feature to
provide only one stroke for the down direction.
•
Slow Speed on Inspection
- (Display shows "SLOW ON INSPECT") Enable this feature
to run slow speed on Inspection. This is normally required if the car speed is 125fpm or
above.
•
Proximity Detector
- (Display shows "PROXIMITY DETECT") Enable this feature if a
Proximity Detector (such as an infra-red curtain) is used. Enabling this feature will
cause the Safety Edge input to be disabled on Fire Service, and the Door Nudging
feature to be initiated while the doors are closing on Fire Service. The Proximity
Detector may be connected to the Safety Edge Input or the Electric Eye Input, as
desired. (The Electric Eye Input is subject to the Timed Electric Eye Cutout and
Nudging, whereas the Safety Edge Input is not.)
NOTE: Door Nudging operation requires an optional Nudging Buzzer output
and Reduced Speed Door Closing output.
•
Short Floor
- (Display shows "SHORT FLOORS") The Short Floor selection applies to
installations with Floor Switches or Pulsing Switches where the floor height is less than
twice the slowdown distance, but more than the slowdown distance plus the leveling
zone. If Floor Switches are used, then the Short Floor Setting should be enabled if the
Floor Switches overlap at any floor. If Pulsing Switches are used, then the Short Floor
Setting should be enabled if the top of any Up target is BELOW the bottom of the Down
