1 Foreword You have purchased a Demag product. These operating instructions are designed to provide the owner with appropriate instructions for safe and correct operation and to facilitate maintenance. Every individual given the task of transporting, installing, commissioning, operating, maintaining and repairing our products and additional equipment must have read and understood the operating instructions the safety regulations and the safety instructions in the individual chapters and sections.
1.3 Liability for Defects These operating instructions must be read carefully before installing and putting the radio control into operation. We assume no liability for any damage and malfunctions resulting from failure to comply with the operating instructions. Any liability claims for defects must be made by quoting the order number immediately on detecting the defect.
1.5 Definitions Owner Owners (employer, company) are defined as a person who owns a radio control and who uses it appropriately or allows it to be operated by suitable and instructed persons. Operating personnel/operator Operating personnel or operators are defined as persons entrusted by the owner of the radio control system with the operation of the radio control.
2 Safety instructions 2.1 Symbol description These symbols are used to warn against potential safety hazards or causes of damage or provide useful information. Hazard warning This symbol appears in the operating instructions next to all instructions relating to safety at work wherever a potential danger to life and limb exists. Follow these instructions at all times and be particularly vigilant and cautious.
The transmission method used by Demag is designed for the most robust and interference-resistant radio transmission between the transmitters and receivers of the DRC range. The state-of-the-art transmission method is provided with technical features (e.g. frequency hopping) which are intended to ensure a minimum of conflicts for radio operation together with other transmitter and receiver devices which use the same frequency range.
2.3 Inappropriate use Certain work and practices are prohibited when using the product as they may involve danger to life and limb and result in lasting damage to the product, e.g.: Manipulating electrical equipment Connecting the unit to power supply with voltage or frequency other than those specified on the type plate Non-compliance with specified mounting positions Non-compliance with the max. permissible ambient temperature.
The DRC-MP radio receiver must be taken out of service immediately if functional defects or irregularities are detected. In the event of a stoppage (e.g. if defects regarding safe and reliable operation are detected, in emergency situations, in the event of operating malfunctions, for maintenance purposes, if damage is detected or after finishing work), the operator/experienced technician must carry out all prescribed safety measures or observe that they are automatically carried out.
3 General description 3.1 Transmitter/receiver interface The DRC-MP radio receiver can either be used with a DRC-10 hand-held transmitter or with a DRC-J joystick control system. Radio receiver DRC-MP Hand-held transmitter DRC-10 Joystick control system DRC J Radio remote control systems of the DRC range are exclusively intended for single-transmitter operation; i.e. there is always a clear assignment between a specific transmitter and its corresponding radio receiver. 3.

5 Putting the DRC-MP radio receiver into operation for the first time 5.1 Assembly and connection of the radio receiver Fitting the radio receiver: Bolt radio receiver housing to location where the receiver is to be mounted (switchgear cabinet, wall, etc.). Connect the receiver to the installation to be controlled by means of the connected multi-pole connection cable. Power supply to the radio receiver is via a connection cable (control voltage). 42365144.eps 42365244.
When fitting the receiver, make sure that the aerial is free to the extent possible (see figure in section 5.1). Any shadows, in particular those caused by metallic parts in the direct vicinity of the aerial, have a negative effect on the max. possible range as well as on the stability of the radio connection between transmitter and receiver. A free view to all sides from the point of view of the receiver aerial on the working range of the assigned transmitter is optimal.
The following illustration shows the positions of the connection terminals inside the DRC-MP radio receiver and the equipment of the PCB. 5.

5.5 Activating and adjusting special functions DRC-MP radio receivers are provided with adjustable special functions to adapt the sequence of switching processes for the control of the drive motors to the application and to feedback information on operating conditions of the installation to the transmitter. The following functions can be set: BE function brake application control for travel motors, see section 5.5.1. Feedback channel information display of feedback channels, see section 5.5.2.
When pole-changing squirrel cage rotor travel motors are switched down from fast to slow speed, unwanted loads on mechanical components and load sway result. It is therefore recommended to use the integral BE (brake application) function in conjunction with the DRC-MP radio remote control system. This ensures that mechanical braking is started when the fast travel speed has been switched off. Only after expiration of an adjustable delay time can the slow travel speed be switched on again. 5.5.

5.5.2 Feedback channel information DRC-10 hand-held transmitters and DRC-J joystick control systems are provided with an integrated display, which can also be used for the display of feedback channel information. To implement this function, the DRC-10/DRC-J transmitter and the DRC-MP radio receiver operate as bi-directional radio systems. This means, that the DRC-MP radio receiver can also send data/information to a DRC-10/DRC-J transmitter.
5.5.3 SGDM function The SGDM function has been developed for high-performance, pole-changing hoist motors to avoid overloads caused by frequent start-up and braking cycles. 1. Starting This function ensures that the motor is always started by means of the winding with the higher number of poles. As a consequence, switchgear and wiring can be of a less expensive design.
5.5.4 LIFT-FAST relay In the default setting, the contact of LIFT-FAST performs the FAST function (for LIFTING and LOWERING). The contact of LIFT-FAST always remains switched off. The LIFT-FAST contact is activated by switching over the DIP switch (see below). Example DIP switch SW1 Changes of the DIP switch settings only become effective when the receiver is switched on again.
5.6 Function check after installation A general function check of the receiver is possible by means of the light diodes in the window of the cover, see also section 5.3. The yellow LED flashes, when the receiver is supplied with current and no hand-held transmitter has been assigned yet. In addition, the red LED flashes, when radio telegrams of transmitters that have not been assigned are received.
