1. DESCRIPTION:
Some permanent magnet machines have several brake disk systems and some of them have a normal
brake at the end of the motor shaft. It is practically impossible for machine designers to implement a
mechanical wire system to open all the brake systems to rescue people.
So, the controller has to incorporate an electrical mean to be able to manually pulse the brake opening
with a selector in case of failure of the motor drive or loss of power in the building.
2. MANUAL BRAKE SWITCH SELECTORS:
The controller incorporates 2 selectors:
 SW10 “MANUAL BRAKE RELEASE”:
That switch when turned to the “ENABLE” position authorizes the manual brake control. This key
will also start the power pack system if there is a total power loss in the building. The controller must
be in “INSPECTION” mode.
 SW20 “BRAKE PULSE”:
As soon as the key is turned to “PULSE”, relays and contactors turn on to open the brake.
The “EBR” contactor will close to short the motor phases thus limiting the car speed.
The emergency brake voltage will peak and hold. The emergency brake will stay opened.
3. RESCUE SEQUENCE:
 Leave the main switch disconnected to the “CLOSED” position.
 Place the inspection switch in the controller to the “INSP” position.
 Turn the “MANUAL BRAKE RELEASE” to the “ENABLE” position.
 The power pack will start if there is no power in the building.
 The LCD will show the car-relative information in manual brake release mode such as car
position, perforated tape position, speed and car direction.
G-1
 Car direction depends on its load, so the car can be either going up or down.
 Before pulsing the selector, it is important to observe the position, car speed and door zone state on
the LCD. When the door zone is detected (DZO = YES), the brake pulse will automatically stop and
no other movement will be authorized as long as the DZO signal is activated. The car door can then
be manually opened if there is a main power loss.

Information shown :
 IND = Current floor where the car is at.
 P = Perforated tape actual position (only if the control is using perforated tape).
 S = Actual car speed in ft/min (only if the control is using perforated tape).
 If traction, the last line indicates the state of the signals sent to the drive.
 FOW = Forward.
 REV = Reverse.
 STP = Stop.
 DZO = YES if the door zone sensor DZO is activated and NO if the sensor is not activated.
 The pulsing time is limited by the program in DM 0005 to modify the time given to keep the brakes
open; this delay can be changed if needed (1.0 to 5.0 seconds).
 It is now possible to pulse the brake coils to move the car.
 Turn the selector SW20 on « PULSE BRAKE ».
 Check the info on the LCD: position, speed, direction and DZO signal.
 When the DZO = YES, stop the brake pulse sequence.
 Manually open the door.
IF THE CAR SPEED IS VERY LOW, YOU CAN OPEN 1 PHASE OR BOTH PHASES ON the EBR
CONTACTOR.
 When finished, you have to turn all selectors to “OFF” and place the inspection switch to
“NORMAL”.
4. WEEKLY AUTOMATIC POWER PACK CAPACITY DIAGNOSTIC:
Every week the controller will start and test the power pack to be sure of its condition. This test sequence
can be done during the day. The controller will start the power pack and cycle five 3 second pulses with
a 4 amps current at 120 VAC. During this test, the car can function normally because the brake is not
pulsed and the test is made in a resistor.
IF FOR ANY REASON THE POWER IS FOUND TO BE NON-OPERATIONNAL, THE
CONTROLLER WILL STOP THE ELEVATOR AND AN ERROR CODE WILL BE SHOWN.
THE BOTTOM CAR CALL LIGHT WILL FLASH.
THE MANUAL RESET BUTTON RESETS THE ALARM. THE ELEVATOR CAN RESTART UP
TO THE NEXT TEST PERIOD, WHICH LEAVES ONE WEEK TO FIX THE PROBLEM.
G-3
Refer to the Reynold user manual for power pack troubleshooting.
Time of the week for the test period:
DM 0387: Day of the week to perform the automatic test (O for SUNDAY, 6 for SATURDAY).
DM 0388: Start of the testing period HHMM (From 0000 to 2359).
DM 0389: End of the testing period HHMM (From 0000 to 2359).
DM 0394: Number of test sequences performed since the last user registered reset.
The LCD menu will show you the actual time.
You can also check:
 D385 = Day of week
 D381 = Actual HHMM.
If the plc clock time has to be changed, go to the LCD menu to change it. Or, for groups with separate
dispatch, go to the clock menu in the menu bar.
It is best to configure the power pack test during weekdays work hour because the elevator will shut
down if the test fails.
EXAMPLE:
THE CONTROLLER WILL VALIDATE THE VALUES ENTERED AND WILL FORCE TUESDAY.
09:30 TO 11:00 AM IN CASE OF A BAD ENTRY.
DM 0387 = 2  TUESDAY
DM 0388 = 0930
DM 0389 = 1100
The adjustor can select the time of the week where the test can performed.
CAUTION
For elevator groups (2 cars or more), do not program the test period for all cars at the same time,
space out the time period between each elevator.
4.1.
POWER PACK CAPACITY MANUAL TESTING:
 Verify the actual time of the controller:
 D385 = Day of week
 D381 = Actual HHMM.
G-4
 Change registers:
 DM 0387 = Same value as DM385
 DM 0388 = 0400
 DM 0389 = 2300
After 10 seconds the test will start. You will see “TRR” relay turning “ON”. You can see
“RRTS” relay cycle 5 times and if the test passes, everything will end without error. If the test
fails, the elevator will shut down and the error code HR82.15 “EMERGENCY BRAKE FAULT”
will be shown on the LCD.
IF THE EMERGENCY UNIT TEST FAILS, THE ELEVATOR WILL SHUT DOWN AND AN
ERROR CODE WILL BE SHOWN.
THE BOTTOM CAR CALL LIGHT WILL FLASH.
THE MANUAL RESET BUTTON RESETS THE ALARM. THE ELEVATOR CAN RESTART UP
TO THE NEXT TEST PERIOD, WHICH LEAVES ONE WEEK TO FIX THE PROBLEM.
