4.6. Optional Service and Feature Descriptions
The Ethos Two has a multitude of standard methods of control built in, the feature list below gives a brief description
of the main services and features. Some of these features require additional external circuitry so need to be
requested at panel build time.
Access to the feature settings can be found behind the MMI “Settings” button.
Press: Settings → Search Settings → Services / Features
Accelerometer
The 3 axis accelerometer mounted on the Car Module board can be used to report abnormal stops or an “Over G”
event.
Anti-Nuisance Control
Monitors the lift use to determine if inappropriate call inputs are being set.
Auto Recovery
If the controller senses a fault and has tried 3 times to start a journey or door cycle it will go out of service, the auto
recovery feature extends the number of attempts to move.
Auto Run / Burn In Test
Auto Run can be used to test the lift for up to 24 hours before it’s entered into service, in this mode car calls will be
entered automatically, this feature can be used with or without door disable.
Bus Stop / Dispatch Failure
If the controller cannot accept landing calls due to a group bus fault or landing push feed fault it will go on to bus
stop mode to allow a limited service.
Cabinet Fan
Limits the cabinet fan to between certain hours if needed.
Outputs: "CFAN ", "Cabinet Fan"
Car light Control
Car light control used to turn off the lift car’s fan and light when the lift is not in use.
Outputs: "CLT ", "Car Light Output"
Eco Mode
Programmable by time of day, with staged count down timers, when active.
Any ‘Wake-up’ signal will cancel Eco-Mode and return the lift to normal service.
Wake-up signals include car or landing calls, special service, fire control, inspection operation and touch screen
activation. Stage 1 (Snooze) after an adjustable period of inactivity. The car light and fan will be switched off. Stage
2 (Sleep) after a second period of inactivity. Shutdown drive and unneeded control circuitry, turn off unnecessary
LEDs and backlights. Stage 3 (Hibernate) after a third period of inactivity. Shutdown indicators, speech, call button
dual-illumination and other peripherals.
During activated Eco-Mode periods, the controller will select the “Low Energy” ride profile, this is used if calls are
below an adjustable level or the lift is on a homing run or other non-critical journey. Low Energy mode is deactivated
if multiple calls above the call limit are accepted.
Outputs: "EC1 ", "Eco Mode Stage 1" + "EC2 ", "Eco Mode Stage 2"
Emergency Power
On ESUP input activation: -
Puts all cars in emergency power mode, so they stop at next floor and wait for next command. Lifts will display
Emergency Power in the Mode entry on the status screen.
If the car does not have the duty flag, it will additionally display No duty Car as a fault in the status button.
Dispatcher then selects Duty Car: -
If dispatcher sets “duty car” across the network then we follow the next three inputs or flags from dispatcher. The
dispatcher gives duty to a car; this would then return to either the fire floor or the emergency return floor if FSR, FAM
or EMR are active. If not the dispatcher will request a recovery to the emergency supply return floor. The recover
flag from dispatcher causes the car to return to emergency supply floor only if duty car. FAM or FSR would also
return to fire floor only if duty car. EMR would return car to emergency floor if duty car.
FSR (Firefighting) phase 2: -
