Mounting two bar code tapes with the same value range
For crane systems or elevators, two bar code tapes with the same value range are used for positioning.
If a twin tape is not used: To have the same values at the same position, one bar code tape must be affixed
with numbers upside down while the other is affixed normally (see figure 6.7).

The BPS can be mounted in the following ways:
• Mounting using a mounting device on the fastening grooves
• BTU 0300M-W: Wall mounting
• BT 56: Mounting on a rod
• Mounting using a mounting device on the M4 mounting threads on the rear of the device
• BT 300 W: Mounting on a mounting bracket
• BT 300-1: Mounting on a rod
• Mounting using four M4 mounting threads on the rear of the device

A twin tape always consists of two bar code tapes.
When ordering twin tapes, two bar code tapes are always included with an order.
Ensure that the BCB is affixed without tension.
The BCB is a plastic tape that can be stretched by strong mechanical tension. Excessive mechanical
stretching results in lengthening of the tape and distortion of the position values.
