2. Locate the battery compartment on the rear of the T8B unit.
3. Open the battery compartment cover.
4. Insert the charged battery, ensuring correct polarity.
5. Securely close the battery compartment cover.

4.3. Mounting and Connecting the ACRH11 Receiving Unit

The ACRH11 receiving unit should be mounted in a secure location on the crane or machinery, protected from excessive vibration and direct impact. Connection to the crane's electrical system should only be performed by a qualified electrician.

• Mount the ACRH11 unit using appropriate hardware, ensuring it is stable and accessible for maintenance.
• Connect the power supply (24-220V~ 50-60Hz, 0.8A) to the designated terminals on the ACRH11.
• Connect the control outputs from the ACRH11 to the crane's control inputs according to the crane's wiring diagram and the ACRH11's connection interfaces (cable gland M20 and M25, plug 16 and 24 pin).
• Ensure all connections are secure and properly insulated.

5. Operating Instructions

5.1. Powering On/Off

• To power on the T8B transmitting unit, press and hold the designated power button (if applicable) or follow the specific power-on sequence.
• The ACRH11 receiving unit will power on automatically when connected to the crane's power supply.
• To power off the T8B transmitting unit, press and hold the power button until the unit shuts down.

5.2. Basic Control Functions

The T8B transmitting unit features various buttons for controlling crane movements:

• Directional Buttons: Used for controlling movement in specific directions (e.g., up/down, left/right, forward/backward).
• START Button: Initiates the control sequence or activates specific functions.
• AUX Button: Used for auxiliary functions, which may vary depending on the crane configuration.
• GSS (General Safe Stop) Button: A safety function that brings the crane to a safe stop.

5.3. Emergency Stop (EMS)

The red Emergency Stop button on the T8B transmitting unit is a critical safety feature. In case of an emergency or unsafe condition, immediately press this button to halt all crane operations. The EMS function is designed to meet SIL 2 / PL d; cat. 3 performance levels.
