3.  FUNCTIONAL DESCRIPTION 

 

•  The main contact (MC) is a normally open high-side dual switch connected to UB.  The main contact 

will turn off after all transmitter buttons are released (time is based on H-Link programming). 

•  D3 – D14 and P1 are internally powered by the main contact. 
•  D1, D2, D15, and D16 are powered by VSW.  Main contact may be connected to VSW for safety 

operation of these signals if desired. 

•  D1 – D16 are high-side switched outputs and are fully programmable with the H-Link (on/off delay, 

NO/NC, latching, DK/logic assignment, input/output interlocking). 

•  In DK1 Static Mode, any received DK will activate the main contact if no error is detected.  In DK1 

Pulsed Mode, the main contact will only activate if DK1 is received.  Any other DK received in Pulsed 
Mode when the system is not started will trigger an error. 

•  DK1 may be used to clear previous system errors. 
•  The STOP function will clear all outputs (MC, D1-D16, P1) immediately. 

•  Short circuit protection is activated if voltage is detected on the main contact output while the circuit is 

not active.  If a main contact short circuit is detected the system will enter an error state. 

•  DIN1-4 are digital inputs.  They can be configured via H-Link for NO/NC, interlocking, and 

interlocking delay operation. 

•  AIN1-4 are analog inputs.  They can be calibrated for use in arbitrary unit conversions and configured 

as digital inputs 5-8.  In digital mode, the high/low threshold is adjustable. 

•  Analog input error is detected if an analog channel is 0V or greater than 5V.  This can be used to select 

a PWM speed on open or short circuit detection. 

•  P1 is the PWM output.  The min/max values, dither amplitude, dither frequency, speed settings, and 

speed selections are adjustable via H-Link. 

•  PWM speeds may be selected using a logic AND function with a digital output, digital input, analog 

error, load percentage, or logic gate result. 

•  A feedback telegram is transmitted immediately after a control telegram is received.  In repeater mode, 

this will be followed by repeating the control telegram. 

•  The system includes a load-limiting calculation function.  The coefficients for the equation, analog 

sensor calibration, analog sensor mapping, and load vibration feedback pulses are configurable via H-
Link and may be monitored using online status mode.  The system load status may be used to select 
PWM speeds or interlock digital outputs. 

•  The system provides a “boost” function to allow user overrides during overload conditions.  Boost 

PWM speed settings, load interlocking override, maximum boost load percentage, and boost 
on/off/wait times are provided via H-Link. 

 
3.2. Learning Function 
 
The receiver has a learning function that allows the user to set the receiver’s address and channels to a 
transmitter’s without the need for an H-Link programmer.  To use the learning function follow these steps: 
 
1.  Press and hold START (DK1) on the transmitter. 
2.  While holding START press and hold the learning button on the receiver. 
3.  The Green LED will begin flashing when learning is complete.
