Page 4: Analog Inputs
KV SERIES HARDWARE MANUAL WWW.EMTRON.WORLD 1.0 Analog Inputs The KV series supports up to 24, 12-bit high resolution analog input channels. KV ECU Analog Inputs KV12 KV16 KV16M 1.1 Analog Input Channels 1- 16/24 All analog input channels are sampled using high resolution 12-bit analog to digital converters with a 0.0 - 5.000V input range. -

2. The ECU uses “True” zero crossing detection on magnetic based signals. This gives precise 0V crossing detection, critical on magnetic sensors used in VVT control. 3. Emtron Scope function is available on Digital Inputs 1-4. © EMTRON AUSTRALIA PTY LTD JUNE 2018... -
Page 9: Arming Threshold Control - Magnetic Sensors
Below is a scope trace showing a signal over one cycle, scaled at 2V/Div. A conventional oscilloscope or the Emtron scope can be used to view a signal to best determine the correct arming thresholds. The preferred method is to find the lowest amplitude during one cycle (highlighted by the red circle below) and make the arming threshold 60% of that value. -
Page 10: Digital Input Channels 1- 14 - Switched Input
The current can be worked out using Ohms Law: V = I x R. Measure the voltage at the pin with the switch OFF, typically around 9V. Resistor = 4700 Ohm Current (I) = 9V / 4700 = 1.9mA © EMTRON AUSTRALIA PTY LTD JUNE 2018... -

Page 13: Auxiliary Output 9-12 - Half Bridge
▪ Electrostatic discharge (ESD) protection ▪ Reverse battery protection ▪ Half Bridge 15.0A continuous (pin limited). Can be used as Low Side, High Side or paired with another channel for DC motor control (DBW) © EMTRON AUSTRALIA PTY LTD JUNE 2018... -
Page 14: Auxiliary Outputs - Full Bridge Configuration (Dbw)
For KV12 and KV16, 4 channel DBW applications the following output pairing is required: ▪ DBW3, it is recommended to pair Auxiliary 13 and Auxiliary 14 outputs. ▪ DBW4, it is recommended to pair Auxiliary 15 and Auxiliary 16 outputs. © EMTRON AUSTRALIA PTY LTD JUNE 2018... -
Page 15: Auxiliary Output - Flywheel Diodes
For this reason, the boost control modulation frequency should be kept below 30Hz. Typical values are 15 – 20Hz. © EMTRON AUSTRALIA PTY LTD JUNE 2018... -
Page 16: Transmission Brake Solenoid
Auxiliary channels 13-16 are the only outputs with enough current to power such solenoids. It is strongly recommended to run an external flywheel diode to prevent long term ECU damage. If the output is modulated a flywheel diode MUST be installed (See Emtron www for details). -
