2. Elevator car control panel
– Standard OKR, vertical orientation, with fixed REC
– Standard OKR, vertical orientation, with movable REC
– Extended OKR, with fixed REC panel
– Extended OKR, with movable REC panel
Tip:
OKRs with a fixed REC panel come in two types:
1. REC is on the left side or
2. REC is on the right side
The OKR can be selected based on its position on the car top to maintain a safe distance of 300 mm (placement mark equal to or less than) between the REC and the car top (EN81-20 clause 5.4.8.a).
2.1. Standard OKR, vertical orientation, with fixed REC panel.
If the local standard is EN81-20/50, then this type of OKR should be selected, and the following optional features are not required:
– Elevator car card reader interface
– Third-party peripherals
– CANGIO circuit board
– NGC power supply
The available models are as follows:
– REC is on the right side
– REC is on the left side
The decision to use the REC on the right or left side depends on the vehicle's roof layout and the OKR position.
The image above shows the REC unit on the left, in the OKR configuration, without a maintenance cover.

It includes:
– Display (SMLCD)
– Keyboard
– Plastic case
1 TSD21 Reset Button (lockable), for SPH elevators
2 Reset Button
3 SMLCD
4 Elevator Fault
5 LUET (Door Zone)
6 LZS: KNET Feedback
7 Overspeed Test
DVB = Trigger
DNB-A = Reset
8 Car Automatic Positioning - Car Top Maintenance
9 Down Maintenance Button
10 Enter Button
11 Scroll Down Button
12 Maintenance Mode
13 Scroll Up Button
14 Exit Menu Button
15 Up Maintenance Button
Tip:
Press the reset button for less than 1 second for a software reset.
Press the reset button for more than 5 seconds for a hardware reset.
A hardware reset clears temporary software flags.
Items 10, 11, 13, and 14 are referred to as SMLCD navigation buttons.
3.2. Keyboard Shortcuts
The following special key sequences can be used as shortcuts to quickly access specific menu items (these are not context-sensitive and are always available).
| Key sequence | operate |
| ESC + UP | Pressing both buttons simultaneously provides direct access to the Status Lift (elevator status) display. |
| ESC | Using the keyboard shortcut ESC + UP, you can return from the Status Lift (elevator status) screen to the location where you previously accessed the elevator status. |
| ESC + OK | Pressing both buttons simultaneously will directly access the in-car elevator call function (the original position in the menu tree will be restored after the elevator call is completed). |
| ESC + 2x UP | Press and hold the ESC button, then press the UP button twice to initiate an explicit logout. |
| ESC + DOWN | Pressing both buttons simultaneously allows you to return directly to the current submenu from a lower-level activity. |
| UP + DOWN | Change the editing mode to enter values (parameters): Editing Mode 1: Scroll through the entire range. Editing Mode 2: Scroll through individual digits. |
4. SMLCD
SMLCD is the display screen for the HMI (Human-Machine Interface) and serves as the user interface for the CO SC controller.
