4. FUNCTIONAL DESCRIPTION 4.1. General Description • This transmitter is designed to transmit with RF-transmission duty cycle of 1%. • The transmitter will turn off automatically 2 seconds after all buttons are released. • STOP (S1) is an emergency stop button that has priority above all other buttons. • START (DK1/2) is a start or horn function. This button can be used to reset error in the receiver (Overload/ Main Contact error). • DK3-8, DK11-13 are regular digital channels 4.2. Switch Error Detection The transmitter unit has a function that detects when a switch is broken. If a switch is active when a battery is inserted the unit will go into an error state. The Red LED will come on and stay on until the active switch is turned off. 4.3. Low Voltage Indicator The unit has a low battery detection function. Once the battery level becomes low, the Red LED will come on solid while the Green LED keeps blinking with every telegram. If the voltage level reaches a critical level, the transmitter will only send Emergency Stop telegrams. 4.4. LED Description Green Flashing: Telegram Transmitted Red ON, Green Flashing: Low Voltage Pre-Warning Red Flashing: Emergency Stop Transmission Red Flashing/Green Flashing at 500ms interval: Memory Error Red Solid (on power up): Switch Error
