MoTeC PDM30 - Manual (Page 20)

MoTeC Configuration 17
Output Pins Master Shutdown
The Master Shutdown feature turns off all outputs that are configured for
Master Shutdown, while a user configured channel is true.
Any PDM channel can be used as the Master Shutdown channel.
Each output pin can be individually configured to support or ignore the Master
Shutdown channel.
Keypads
Up to four MoTeC CAN keypads can be configured to work with the PDM.
The global keypad setup configures the overall keypad settings. Individual
keypad buttons are configured under the Keypads in the Configuration Tree.
The Keypad Name is a description of the keypad (eg. “Main Keypad”).
The Keypad Type determines how many buttons will be shown in the keypad
button configuration.
The keypad Node ID and CAN Addresses must match the settings
programmed into the keypad. Keypads are supplied by MoTeC pre-
programmed with default settings for Keypad 1. The Restore Defaults button
will select the default settings for the particular keypad.
The Brightness Control settings allow the keypad backlight and LED
brightness to be set to a specified level. An alternate brightness level and
condition can be specified to allow day/night operation.
Input Pins
Configuration of an input will create a Status and a Voltage channel. Both
channels can be used in a condition or to directly control an output. They are
transmitted via CAN.
To configure an Input Pin

In the Configuration Tree, select Input Pins

Double click the input to setup

Type a channel name and select settings as required
The trigger voltages are fully programmable. The recommended trigger
voltages are approximately 3.5 V for the low threshold and 4.2 V for the high
threshold. The high threshold should be set below 6 V to ensure detection of a
high level signal when the battery voltage is low.
To avoid switch bounce and/or to delay recognition when the switch changes
state, the inputs also have programmable trigger times. A trigger time of 0.1
second will normally reject switch bounce.
