1.

Starting Up Conditions

Starting up of OVF20 system only should be performed by authorized personnel. Caution: Opening of the package has only to be done for reasons of repairing and may only happen if you have checked by measurement that the main switch is off and the value of DC link voltage is <60v. The controller cabinet has to be mounted in a distance of 50mm between wall and the heatsink of the drive. The mechanical works of hoistway and cabin as well as machine room and hoistway installation have to be finished to ensure inspection run. The electrical connections have to be final installed and checked. Attention: Do not bridge safety devices and door contacts.

First Inspection Run (without Encoder) CHECKING OF VOLTAGES

Switch the unit to ERO operation Switch on the main switch Check the power supplies according to the diagram in TRF1 After switching on, the DR (drive ready) signal on the MCB II must be active, (checking by SVT), it indicates the readiness of the inverter (at MS300 and MCS310 OP relay will energise). 5. It must be checked if the following inputs of the MCB II have the correct voltage of 24VDC. - P3.2 (24V output) - P4.7 (/1LS signal) - P4.8 (/2LS signal) - P3.1 (DBD signal) in each case to P3.3 (HL2)

INPUT SIGNALS CHECK ON THE MCB II USING THE SVT

Connect service tool to MCB II. With module 1, 2, GO ON, check input signal DBD.

2.3

SET OF DEFAULT VALUES

By setting of standard values significant parameters are adjusted for starting up. Activation is due to by:Module, 3, 6, ENTER Remark: For runs in INS or ERO mode also the correct controller type (CONTR TYPE) and correct contract speed (CON SPE) have to be adjusted, M 3 1 GO ON. As inspection run without encoder is further possible if the number of impulses (ENCODER PULSES) is set to zero.

2.4

CHECK OF DIRECTION

After setting of standard parameters you should check the run direction with the ERO box. For INS or ERO operation the MCB II needs the input signals UIB or DIB, M 1 2 GO ON. The mains contactors SW1 and SW2 have to be activated. The activation is done by the MCB II in connection with UP or DOWN signals if the safety chain is closed. In the same time the DBD input will be inactive. With the service tool the status of the drive can be controlled, M 1 1 GO ON. By pushing of UIB or DIB buttons the motor will start. If the run direction is not the same as the wanted direction, then two conductors of the motor cable have to be exchanged. You must check if the drive reduces speed to creep speed when the cabin reaches the switch 1LS or 2LS (only by MCS220). If the car does not move the error can be detected by means of status display. If shut down (SHT DWN) is displayed the reason can be found out by means of error logging (ErrLog) M 2 2 1 GO ON. By off and on switching of the main switch in decided cases of shut down the blocking can be cancelled.

Adjustment of Magnets

Magnets with a length of 170 to 250mm can be used. At shorter landings you have to consider that the distance between door zones must be at least 180 mm. Otherwise the door zones cannot be separated with normal speed.

In controllers with learn run, the stopping distance is generated by the MCB II software.

* At controllers with learn run no IPU/IPD and SLU/SLD signals are required.

Note: Following problem can occur at correction run, when the distance 1LV up to 1LV and 2LV is too long at creep speed. With it the door zone was not detected and the car runs to the limit switch (7LS). The solution is, the magnets 1LV and 2LV have to be pushed together so far as the failure does not occur.

Connection of Speed Encoder

Several encoders can be connected:1. one channel encoder 2. two channel encoder The SCLK inputs are provided for 1 channel encoder with maximum 350 impulses/rotation. CLKA and CLKB are provided for connection of 2 channel encoders with maximum 2 x 1024 pulses/rotation. If encoders are used with shielded wiring the screen has to be connected on both sides ie., on the connector P9.1 on the MCB II respectively on PE from motor. MCB II Inputs P5.5 EGND P5.6 +15V (max 100 mA) P5.1/2 SCLK1 or 2 for 1 channel encoder* P5.3 CLKA for 2 channel encoder P5.4 CLKB for 2 channel encoder P9.1 ESCR screen * SCLK1 = with resistor 1 kOhm serial SCLK2 = directly input maximum input current 10 mA 10 mA 10 mA

Test inspection run with encoder (before you have to set CONTR TYPE, CON SPE, ENCODER PULSES and ENCODER TRACES) Check the speed The drive is ready now for normal runs for controllers without learn run.

5.

Learn Run

At units with integrated MCS 200 or MCS 220M controllers with learn run the learn run has to be performed. Normal runs are not possible without previous learn run. A repetition of the learn run is necessary if a door zone magnet was removed or if the parameter CON SPE was changed. Before starting the learn run, the parameters CON SPE, CONTR TYPE, TOP FLOOR and FLOORS in 1LS, M 3 1 GO ON, have to be adjusted. Check the 1LS distance before starting the learn run.

Final Adjustment of the Drive

Following parameters have to adjust fundamental for each unit. - Contract parameter (drive parameter will be adjusted automatically by setting of the parameter CON SPE for normal runs) - Vane parameter (have to be adjusted at normal run) - Drive parameter (additional parameter for short runs or manual adjusted speed profiles)

CONTRACT PARAMETERS
NOM FREQU CON SPE = 500 for 50 Hz = 600 for 60 Hz (nominal frequency of the motor) = Contract speed at nominal frequency, given by mechanic (gear, traction sheave and so on)

Attention: For parameter CON SPE a calculation is necessary. CON SPE = (sheave diameter x 50 Hz * x

VANE PARAMETERS M 3 3 GO ON (NORMAL RUN WITH ENCODER)

For the following normal runs the input signals NOR (NORMAL) UIB, DIB and U or D and T for MCS310 and MS300 or V1-V4 for Otis 2000 will be used. Before adjusting the vane parameters (hoistway signals), a trip through hoistway signals should be done (inspection run). The switching of IPU/IPD, (SLU, SLD), LV, (1LV, 2LV) 1LS and 2LS switches should be watched with the service tool M 1 2 GO ON. After this test the vane parameters should be adjusted (hoistway variable). The next step is to search a ‘adjusted floor’ in the middle of the hoistway. 6.3.1 LV DLY UP and LV DLY DOWN (adjustment of floor level)

Check the floor level in down and up direction. Stopping failures will be removed by changing the parameters LV DLY UP (mm) (stopping failure direction up) and LV DLY DOWN (mm) (stopping failure direction down).

If the car is stopping too early (before level), this value has to be higher (+ the stopping failure in mm). If the car stopping too late (after level), this value has to be lower (- stopping failure in mm). If the magnets are adjusted in the same manner at each floor, the car should stop correctly in each landing, otherwise the magnets should be adjusted accordingly. 6.3.2 IPU/IPD DLYU (adjustment of creep time) only at controller without learn run

The creep time (CREEP TIME) should be 300ms – 500 ms. Adjustment is done by changing the parameters IPU DLY and IPD DLY. If the creep time is too long, these values should be increased. The minimum value for IPU-DLY and IPD-DLY depends on the contract speed of the car. The creep time of the last run is displayed in SVT display (right, above) unit 10 ms steps. If the deceleration is started by limit switches in the terminal landings, 1LS/2LS is displayed in the SVT display. Attention: Each IPU/IPD signal must be active for longer than 150 ms (else MLS:/T <> IP, would be registered) Speed 0,5 m/sed 0,63 m/sec 0,8 m/sec 1,0 m/sec 6.3.3 Min value 50 mm 63 mm 80 mm 100 mm

1LS, 2LS (Adjustment of deceleration limit switch)

1LS DLY and 2LS DLY have to be adjusted in the way that in the top and bottom landing the deceleration will be activated by the IPU or IPD signal. If the deceleration started by the limit switches in the terminal landings, a > is displayed in the SVT display. Increase the value for 1LS DLY or 2LS DLY, until the > character, after a new run, does not occur. The value should not be too large for a sure deceleration by correction run. 1LS and 2LS DLY have to be increased, till the failure MLS: 1LS INI DEC in the bottom landing and MLS: 2LS INI DEC in the top landing, while stopping, is removed. Only at correction runs this failure is allowed and can be read in the event logging (ErrLOG = 2 M 2 2 1 GO ON). Conditions in the event logging does not generate automatically a shut down of the unit. The explanation of the events are described in the chapter, Service tool user guide. The unit should be switched off and on (main switch) to reset the event logging counter. If requested you can find the saved events in the menu, Saved (M 2 2 2). At following test runs no failure should be registered in the event logging. Exception: DRV: SPEED MSMT and SYS: Calc time.

6.3.4

Short Landing distance adjustment only at controllers without learn run

SLU/SLD switches can use the same track as LV/IPU/IPD. All switches will be triggered by a positive edge.

Attention: Note adjusted parameter and lie them down in the controller. Store the parameter set up with M 3 7 in the EEPROM. Do not choose the default values, otherwise the adjusted contract specific parameters will be lost. It is helpful to store adjusted parameters in the controller cabinet, because with that the drive can be readjusted rapidly after change of EPROM or MCB II and setting of default values.

In some cases also vibrations at creep speed Too much decreasement could implicate too much pro torque at motoric load

Cause Too less pre torque at motoric load (rollback) Too much pre torque at generatoric load (starting jerk) Too less starting torque at motoric load (roll back)

Too much starting torque at generatoric load (starting jerk) Brake opens too early Brake opens too late Friction too great (starting jerk)

7.2

ELEVATORS WITH LOAD WEIGHING (AT CONTROLLERS WITH LEARN RUN)

If the elevator is equipped with load weighing, then the load switches can be used to optimize the start jerk. The load switches are connected to P4.5 and P4.6 (only at CONTR TYPE = 4, otherwise SLU/SLD inputs) and should be adjusted to 25% ie., 65% of full load. The adjustment can be done with empty car in inspection mode:- Run car into top position - Set parameter PREMAG PER to 100 - Start car in down direction. Adjust PRET FREQ so that the car does not move during pre magnetization. Adjust NEG PRET as low as possible - Run car into bottom position - Start car in up direction. Adjust NEG PRET so that the car does not move during pre magnetization. Adjust NEG PRET as low as possible - Set PREMAG PER to the old value

Set PRET SLOP to 2 up to 4 (at 13VTR to 2).

If the start jerk is worse in up direction than in down direction (empty car), then increase parameter Ustart. Too much increment could implicate vibrations at creep speed. The adjustment is finished and the start jerk one person up is reduced significantly.
