The timer is automatically reset in every mode when the output is switched on. In each mode
that the timer is active, the output of the unit must be switched on to arm the timer.
Each contact channel has a contact input for volt-free contacts and a Vdc input for dc
voltages. The Vdc input may be used to trigger the timer from a dc voltage, and will trigger
from either the voltage switching from zero to 24-240Vdc or 24-240Vdc to zero. The voltage
must be connected with positive to the red “VDC” terminal and negative to the blue “COM”
terminal.
