WARNINGS AND CAUTIONARY NOTES
Installation and wiring must be in accordance with the national electrical code, all local
codes, and all elevator safety codes and standards. The 3‐phase AC power supply to
the equipment must originate from a properly fused disconnect or circuit breaker that is
properly designed and sized for the specific controller requirements and the “Short
Circuit Current Rating” listed on the controller. Improper motor branch circuit
protection will void warranty and may create a hazardous condition.
Wiring to the controller terminals must be installed in a careful, neat manner. Stranded
wire conductors must not have strands left out of the terminals. Leaving strands of wire
out of the terminals can create a potential short circuit. All terminals and cable
connectors must be seated properly. (See the IMPORTANT notice on the next page.)
Elevator control products must be installed by elevator personnel who have been
trained in the construction, maintenance, repair, inspection, and testing of elevator
equipment. The elevator personnel must comply with all applicable safety codes and
standards. This equipment is an O. E. M. product designed and manufactured to
comply with ASME A17.1-2016/CSA B44-16 Safety Code for Elevators and Escalators.
It is the responsibility of the installer to ensure that the installation is performed safely
and that the installation complies with all applicable codes.
Proper grounding is vitally important to the safe and successful operation of this
system, and proper grounding should be installed to comply with all applicable codes.
A separate ground wire should be installed from the building earth ground to the earth
ground terminal in each controller. Proper conductor size must be utilized for
grounding. In order to minimize resistance to ground, the shortest possible length
should be used for the ground conductor.
Do not install the controller in a hazardous area where excessive vapors and chemical
fumes are present. Do not install the controller in a dusty area. Do not install the
controller in a carpeted area. The space in which the controller equipment is installed
should be temperature controlled, moisture free, and should be maintained within a
temperature range of 32° F and 110°F.The space in which the controller equipment is
installed should be kept clean. The controller should be kept dry and should not be
exposed to moisture or water condensation. Make sure the power supply voltage
feeding the controller equipment does not fluctuate by more than +/- 10%.
Every safety precaution, whether or not specifically stated in this document, must be
implemented when installing, adjusting, or servicing elevator equipment. All safety
precautions must be followed to ensure the safety of elevator personnel and the general
public.
Use only the correct rated fusing for controller protection. Use of improperly rated
fusing will void the warranty.

viii
IMPORTANT NOTICE
Most of the field connections to GALaxy controls are made using stranded wire. When inserting this stranded
wire into the terminals –especially those for EPD’s (Electrical Protective Devices) – care must be taken to
ensure that all the strands are properly inserted into the terminals. Improper stripping and insertion may leave
strands outside of the terminals. Strands not properly inserted into the terminals may make contact with wires
from an adjacent terminal.
The danger associated with an occurrence as described above has led GAL Manufacturing to recommend that,
for all connections to the Electrical Protective Devices listed in ASME A17.1-2016/CSA B44-16, Requirements
2.26.2.1 through 2.26.2.39, elevator personnel must follow the guidelines listed below:
•Inspect all terminals used to connect Electrical Protective Devices. Ensure that the cage clamp is fully
open before inserting a wire into the terminal block.
•Perform corrective action for wires with stray strands by one of the following methods:
oReconnect the wire with all wire strands correctly installed into the terminal. Visually verify that
no wire strands are outside of the terminal. The conductor should be stripped and inserted
completely into the terminal in such a manner that no more than two millimeters of bare wire is
visible; or
oAttach a ferrule to the end of field wire for safety devices (as pictured below in Figures 0-1 and
0-2) and insert the ferrule into the terminal; or
oUse an acceptable method such as tinning.
•After removal and replacement of any of these field wires, the actual Electrical Protective Device
should be checked for proper operation.

1.4 Selector System
The selector system for the GALaxy controller is an Absolute Position System with an encoded
touchless tape.
1.4.1 Absolute Position System (APS) Selector
The Absolute Position System Selector uses an encoded tape that is read by two independent
cameras. The dual camera device is SIL3 rated to supply position and velocity data over two
independent CAN bus channels. One CAN bus channel connects directly to the MAIN CPU and the
second CAN bus channels connects directly to the NTS processor. During setup both processors learn
the hoistway floor positions and slowdown limits. Each processor’s outputs control signals and door
zone status to the Safety PAL for independent redundancy checking.
This selector system delivers 0.5mm accuracy, 50.8 pulses per inch. A block diagram of the Absolute
Position System is shown in Figure 1-1.

1.4.2 Primary and Secondary Position Feedback
The Main CPU receives position feedback from the channel A camera CAN bus and builds a table of
floor positions and slowdowns for each floor during setup. On a normal run, the Main CPU uses the
slowdown points to initiate a slowdown to the appropriate floor and uses the floor position to determine
the door zone and exact stopping position.
The NTS processor receives position feedback from the channel B camera CAN bus and builds an
independent table of floor door zone positions and normal terminal slowdown limits (UN, UT, DN, and
DT) during setup. On a normal run, the NTS processor uses the NTS slowdown points to
independently remove power from the appropriate run valves as a redundancy to slowdown and stop
the car at terminal landings.
Both the Main CPU and NTS processor outputs door zone and control signals, (SU, SUF, SD, SDF for
the Main CPU and UN, UT, DN, DT for the NTS processor), to the Safety PAL to make hardware-
controlled decisions that the car is safe to run.
To protect the car from hitting the stop ring at a speed greater than 50 fpm in the up direction, two
mechanical switches are wired in the hoistway at the top terminal landing. The first switch actuated

GALaxy eHydro Elevator Controller Section 1 –Product Description

while running up to the top terminal floor is the Terminal Speed Device (TSD) limit switch that directly
removes power from the up fast valve. The top most limit switch is the Terminal Limit Hatch switch
(TLH) that directly removes power from pump motor and all valves.
1.5 Sequence of Operation
Normal elevator operation, Automatic Mode, is selective-collective. When the elevator is traveling
upwards to answer calls, all up hall calls at floors above the car are answered in the order reached by
the car, regardless of the order in which the calls were registered. Upon reaching each landing with a
car call or hall call registered, the car and hall doors at that floor are automatically opened.
The doors stay opened for a dwell time that is field adjustable. There are three different dwell times
depending on whether it is a lobby call, car call, or hall call. The door will close before the set dwell time
has elapsed if a passenger presses the door close button and the minimum door open time has expired.
The door will reopen before it is fully closed if the door open button is pressed, if a passenger pushes
on the safety edge, if the photo-eye light beam is interrupted, or if a call for that floor in the direction of
travel is pushed. The door will close when the door opening condition is eliminated. When the door has
fully closed, the calls are answered.
When all up hall calls and car calls above the car have been answered, the elevator reverses direction
and travels downward to answer car calls and down hall calls placed below the car. The calls are
answered as previously described for up calls. When all calls below a down car are answered, the car
reverses direction to repeat the cycle. In short, an elevator traveling up will bypass down hall calls, and
an elevator traveling down will bypass up hall calls.
In buildings with more than one elevator grouped together, the actual time of arrival, “real time”, is used
to estimate how long each elevator will take to answer a hall call. The elevator that can respond the
fastest takes the call. Real-time based dispatching permits the controllers to quickly respond to actual
demand for elevator service. Some of the criteria used to estimate the time of arrival are as followed:
•Actual elevator floor to floor run times.
•Actual run time to the floor whether it is a multi-floor run or a one floor run.
•Whether the elevator is in or out of service.
•Whether the elevator is in load weigh bypass mode.
•The direction and position of each elevator in the group.
•The average door cycle time at each stop.
•Status of each elevator, accelerating, full speed, decelerating, actual time in motion.
•Number of stops required due to car calls.
•Number of stops required due to previously assigned hall calls.
•System demand.
The above performance criteria are continuously measured and stored for improved accuracy in the
dispatching algorithm. All of the above data is continuously scanned, and the hall calls are reassigned if
the conditions change and another car can respond faster. The ability to measure actual hall waiting
time virtually eliminates long waiting and improves the average hall call waiting intervals throughout the
building.

1.6 Modes of Operation
1.6.1 Reset Mode
Reset mode is initiated when the elevator power is first turned on, or when the system is reset. When
the reset mode is initiated, the controller performs internal tests to ensure that both the car and
controller are electrically operational before putting the car into service. The car will not move until reset
mode is completed. Some of the internal tests that the controller performs are as follows: is the safety
string made up; is the elevator on inspection operation; is the door close limit open; are the interlocks
made up; is hoistway position correct. If all the safeties are made up, and the elevator is on automatic
operation, and it is at floor level, the elevator will go into automatic mode. If the elevator is not at floor
level, it will run slow speed down to the nearest floor, level into the floor, and reset the floor position
count.
1.6.2 Safety String Open Mode
Safety string open mode is initiated when a safety is open. Some of the safeties are listed below:
•Reverse phase relay
•Governor overspeed switch
•Top Terminal Limit Switch
•Pit switch
•Hatch Safety Switch
•Exit Door Switch
•Car Safeties
•Car top stop switch
•Fire Fighters Stop Switch
•In-Car Stop Switch
•Controller Stop Switch
When the safety string is made back up, the elevator will go back to reset mode.
1.6.3 Controller Inspection Mode
The controller inspection mode is initiated by placing the “INS” switch on the 1121 board in the
inspection position (down). Controller inspection mode permits operation of the car from the machine
room. This mode performs the following operations:
•Enables the controller inspection “ENABLE”, “UP” and “DOWN” push buttons
•Door locks are active and must be closed to move the car.
•Pressing the controller “ENABLE” and “UP” pushbuttons causes the elevator to move at
inspection speed in the up direction.
•Pressing the controller “ENABLE” and “DOWN” pushbuttons causes the elevator to move at
inspection speed in the down direction.
1.6.4 Car Top Inspection Mode
This inspection mode is initiated by placing the inspection switch on top of the car in the inspection
position. Inspection mode permits operation of the car from the car top inspection station. This mode
performs the following operations:

GALaxy eHydro Elevator Controller Section 1 –Product Description
1-7
•Disables access top and access bottom hall switches.
•Disables the controller "ENABLE", "UP" and "DOWN" push buttons.
•Door locks and Car gates/locks are active and must be closed or the door lock and gate bypass
switch or switches must be active to move the car.
•Enables the car top inspection station "SAFE", "UP" and "DOWN" push buttons
•Pressing the inspection station "UP" and "SAFE” pushbuttons causes the elevator to move at
inspection speed in the up direction.
•Pressing the inspection station "DOWN" and "SAFE" pushbuttons causes the elevator to move
at inspection speed in the down direction.
1.6.5 Access Mode
The access mode is initiated by placing the key operated access switch located in the car operating
panel to the on position. Access mode allows entrance into the Hoistway by qualified and authorized
elevator personnel for equipment inspection and service. Access to the top of the car is possible from
the top landing, and access to the pit is possible from the bottom landing. Enabling this mode permits
the following operation:
•Enables the access key switches at the top and bottom landing in the entrance door jambs.
•Bypasses the gate switch to allow car movement with the car door open.
•Bypasses the top or bottom landing hall door lock, depending on which terminal access switch
is being keyed.
•Turning the access key switch to the up position causes the elevator to move at access speed
in the up direction.
•Turning the access key switch to the down position causes the elevator to move at access
speed in the down direction.
1.6.6 Independent Service Mode
The independent service mode is initiated by placing the key operated independent switch located in
the car operating panel to the on position, or by placing the controller toggle switch “IND” to the down
position. Independent mode permits operation of the car with an operator. This mode performs the
following operations:
•Hall initiated calls are ignored.
•Hall lanterns and gongs are disabled.
•The doors open automatically and stay open until closed by the operator.
•Closing the doors requires constant pressure on the door close button.
•When the car door is closed, the car answers the nearest car-initiated call in the direction of
travel.
1.6.7 Load Weighing Bypass Mode
The load weighing bypass mode is initiated when the car is loaded to a predetermined percentage of full
capacity, by closing a connection between terminals “LC” and “LW” or from serial communication from a
load weighing device. Load weigh bypass mode allows the car to answer car calls and lighten the load
before answering any more hall calls. This mode performs the following operations:
•Hall initiated calls are ignored.
•All other elevator functions operate as if on fully automatic service.

GALaxy eHydro Elevator Controller Section 1 –Product Description
1-8
1.6.8 Attendant Service Mode
The attendant service mode is initiated by placing the key operated attendant switch located in the car
operating panel to the on position. Attendant mode permits operation of the car with an attendant. This
mode performs the following operations:
•The doors open automatically and stay open until closed by the attendant.
•Closing the doors requires a momentary pressure on the door close button, or the up or down
buttons located in the car operating panel.
•Hall initiated calls are answered unless there is constant pressure on the bypass button.
•Hall lanterns and gongs are enabled.
•The direction of preference can be specified by momentary pressure on the up or down buttons
located in the car operating panel.
1.6.9 Code Blue Hospital Service Mode
Code blue hospital service mode is initiated by turning one of the code blue switches, located at each
floor where medical emergency service is required, to the on position. A car is selected to respond to
the code blue call. That car will perform the following:
•Cancel all car calls
•Any hall calls previously assigned will be transferred to another car.
•If traveling toward the code blue call, it will proceed nonstop to the code blue call floor.
•If traveling away from the code blue call, it will slow down and stop at the nearest floor, maintain
doors closed, reverse direction and proceed nonstop to the code blue call floor.
•If at a floor other than the code blue call floor, the elevator will close the doors and proceed
nonstop to the code blue call floor.
•Once at the code blue call floor, the doors will open and remain open.
•The code blue in car switch located in the car operating panel must then be turned to the on
position. If the code blue in car switch is not turned to the on position within 60 seconds from
the time the doors reach full open on the code blue call floor, the car will revert back to normal
operation.
•Upon activation of the key switch, it will allow the car to accept a car call for any floor, close the
doors, and proceed nonstop to the floor desired.
•The return of the code blue in car key switch to the normal position will restore the car to normal
service.
1.6.10 Fire Service Phase I Mode
Fire service phase I is initiated when the primary smoke sensor is activated, or the fire key switch
located in the hall station on the primary return floor is turned to the on position. The primary return floor
is usually the lobby floor but could be another landing if it better serves the needs of emergency
personnel when fighting a fire or performing rescues. When fire service phase I is enabled:
•The fire emergency return light illuminates, and the fire buzzer sounds.
•The emergency stop switch is disabled when the door closes (depending on code requirement).
•The car travels to the primary return floor without answering any calls, then parks with the door
open. The fire buzzer turns off, but the fire emergency return light stays illuminated.

GALaxy eHydro Elevator Controller Section 1 –Product Description

•If the car is at a landing with the doors open, the doors will close, and the car will return non-
stop to the primary return floor.
•If the car is traveling away from the primary return floor, the car will stop at the next landing, and
then go immediately to the primary return floor.
•Turning the fire service key switch to the bypass position will restore the elevator to normal
service.
•The elevator will perform per ASME A17.1 requirement 2.27.3 unless otherwise specified.
1.6.11 Fire Service Phase I Alternate Return Mode
Fire service phase I alternate return is initiated when the smoke sensor in front of the elevator at the
primary return floor is activated. When fire service phase I alternate return is enabled:
•The fire emergency return light illuminates and the fire buzzer sounds.
•The emergency stop switch is disabled when the door closes (depending on code requirement).
•The car travels to the alternate return floor without answering any calls, then parks with the door
open. The fire buzzer turns off, but the fire emergency return light stays illuminated.
•If the car is at a landing with the doors open, the doors will close, and the car will return nonstop
to the alternate return floor. If the car is traveling away from the alternate return floor, the car
will stop at the next landing, and then go immediately to the alternate return floor.
•Turning the fire service key switch to the bypass position will restore the elevator to normal
service.
•The elevator will perform per ASME A17.1 requirement 2.27.3 unless otherwise specified.
1.6.12 Fire Service Phase II Mode
To initiate fire service phase II, the car must first have been placed in fire service phase I, and, as a
result, be parked at the designated level with the door fully open. Following that, the key operated fire
service phase II switch, located in the car operating panel must be placed in the on position. Fire
service phase II permits operation of the car by a fire fighter. This mode performs operations in
accordance with ASME A17.1 requirement 2.27.3 as follows:
•The doors close only with constant pressure on the door close button, after they have been fully
opened.
•The doors open only with constant pressure on the door open button, after they have been fully
closed.
•Hall lanterns and gongs are disabled. Safety edge and electric eye are disabled
•All registered car calls can be canceled with momentary pressure on the call cancel button
located in the car operating panel.
•All hall calls are disabled.
•To remove the car from fire service phase II the car must be at the fire return landing with the
doors in the fully open position and the phase II switch turned to the off position.
•See ASME A17.1 requirement 2.27.3 for specific operation of fire service phase II.
1.6.13 Emergency Power Sequencing
Emergency Power is initiated when a connection is made between terminals “HC” and “EMP”. This
mode performs the following operations:
•All cars are returned to the bottom floor one at a time, and cycle the door.
•The door open button remains active.

•If a car is selected to run it will go back into normal operation.
•Removing the connection between terminals “HC” and “EMP” will remove the cars from
emergency power operation.
1.6.14 Emergency Power Battery Lowering
Emergency Power Lowering is initiated when power is lost, and the Normal Power Relay drops out.
When this occurs, the power circuit switches to the UPS backup power and activates the EMP input.
This mode performs the following operations:
•The car returned to the bottom floor and cycles the door.
•The car cannot run but the door open button remains active.
•When normal power is returned to the controller, the Normal Power relay is picked removing
power from the EMP input and the car will return to normal operation.
1.6.15 Earthquake Mode
Earthquake mode is initiated upon activation of a seismic switch. This mode performs the following
operations:
•If in motion the car will proceed to the nearest available floor.
•Once at a floor, the car will cycle the doors and shut down.
•The door open button remains active.
1.6.16 Stalled (Low Oil) Mode
Stalled mode is initiated when the elevator has been in run mode longer than the field adjustable anti-
stall timer. This mode performs the following operations:
•Turns off the pump motor and stops the elevator.
•The car is returned nonstop to the bottom floor.
•Upon reaching the bottom floor, the doors cycle, then the elevator is shut down.
•The door open button remains active.
1.6.17 Automatic Mode
Since this is the normal operating mode, the controller automatically enters this mode if none of the
previously described modes are activated, and if no fault is detected. The following operations are
performed in automatic mode:
•The car operates in selective-collective control sequence when answering calls.
•Hall and car calls are functional.
•Hall lanterns and gongs are operational.
•Simplex Cars Park at the last call answered unless simplex lobby parking has been enabled in
the program. In a multi-car group, a car is parked at the lobby if no other demand exists and
parking is enabled.
•The doors remain closed when the car is parked

Section 2 - Installation
2.1 General Information
This section provides basic guidelines and recommendations for the proper installation of the controller
equipment. These guidelines should be used as general instructions. They are not intended to usurp
local codes and regulations.
2.2 Site Selection
There are several factors that elevator personnel should consider when choosing a location for installing
this product. The elevator controller should be installed at a location that provides the most convenient
access for adjustment, inspections, and repairs. If at all possible, elevator personnel should have an
unobstructed view of the machine when standing in front of the controller. A safe and adequate
workspace around the controller must be provided. Work areas must be free of any items that might
interfere with the proper routing of conduits or hinder the opening of cabinet doors. All clearances,
workspaces, lighting, and guarding around the controller must comply with governing codes.
2.3 Environmental Considerations
The controller package is provided with a standard type 1 enclosure. This type of controller should be
installed in a clean, dry, and non-corrosive environment. Ideally, the equipment room should be
temperature controlled between 70° F and 90° F. However, control equipment will function properly within
an ambient temperature range of 32° to 110° F. If temperatures remain at the upper and lower extremes
of this range for an extended period of time, the life expectancy of the control equipment may be reduced.
It is important to always keep the controller dry, clean, and free of any dust and debris.
The control system is designed to have a high immunity to electrical noise, radio frequency radiation, and
magnetic interference. However, high levels of these items could cause interference with certain parts of
the control system.
The power supply feeding the controller should have a fluctuation of no greater than + or - 10%.
2.4 Wiring Guidelines and Instructions
See the IMPORTANT NOTICE on page “viii” of this manual

2.4.1 Wiring Schematics
A complete set of wiring schematics and connection diagrams will be provided for each job. Each set of
wiring schematics and connection diagrams are job specific. The job name and number will be listed in the
bottom right corner of each page of these documents.
2.4.2 Proper Field Wiring
Most of the field connections to GALaxy controls are made using stranded wire. When inserting this
stranded wire into the terminals –especially those for EPD’s (Electrical Protective Devices) – care must
be taken to ensure that all the strands are properly inserted into the terminals. Improper stripping and
insertion may leave strands outside of the terminals. Strands not properly inserted into the terminals
may make contact with wires from an adjacent terminal.
The danger associated with an occurrence as described above has led GAL Manufacturing to
recommend that, for all connections to the Electrical Protective Devices listed in ASME A17.1-
2016/CSA B44-16, Requirements 2.26.2.1 through 2.26.2.39, elevator personnel must follow the
guidelines listed below:
•Inspect all terminals used to connect Electrical Protective Devices. Ensure that the cage clamp is
fully open before inserting a wire into the terminal block.
•Perform corrective action for wires with stray strands by one of the following methods:
oReconnect the wire with all wire strands correctly installed into the terminal. Visually
verify that no wire strands are outside of the terminal. The conductor should be stripped
and inserted completely into the terminal in such a manner that no more than two
millimeters of bare wire is visible; or
oAttach a ferrule to the end of field wire for safety devices (as pictured in Figures 0-1 and
0-2) and insert the ferrule into the terminal; or
oUse an acceptable method such as tinning.
•After removal and replacement of any of these field wires, the actual Electrical Protective Device
should be checked for proper operation.
2.4.3 Ground Wiring
Proper grounding of the power supply, controller, elevator car, and hoistway is required. Separate
conductors should be run for EG (earth ground) and GND terminals. These terminals and conductors
are detailed on the wiring schematics.
2.4.4 Hoistway Wiring
All hoistway wiring is detailed on the wiring schematics and connection diagrams. The number of
required hoistway conductors is listed in the connection diagrams. A job specific “pull sheet” is also
included in the connection diagrams.
