TIME DELAY SETTINGS - STANDARD
This setting will delay the time between when the VRF II Series senses material and the main relay changes
state. The delay is only in this direction, regardless of fail-safe setting. There is no added delay when the
material leaves the probe. There is a fixed internal delay when material leaves the probe and this delay varies
from 1 to 3 seconds as the sensitivity is changed from lowest sensitivity (high vibration) to high sensitivity (lowest
vibration). Duration of an additional delay is determined by SW1 Positions 3, and 4 as described in the table
below. The VRF II Series is factory set for the minimum delay.

TIME DELAY SETTINGS - ADVANCED
The time between when the VRF II Series senses material, or its absence, and the output relay changes state
is field programmable using SW5 positions 2 & 3. The delay can be in either or both directions, regardless of
the fail-safe setting. Duration of the delay is determined by SW4 and SW5 position 5. The functionality of each
switch is shown in the tables below.
SW5 Position 2
Delay Mode
ON
The selected delay by the SW4 is applied when material touches the probe
OFF
There is no delay when material touches the probe
SW5 Position 3
Delay Mode
ON
The selected delay by the SW4 is applied when material leaves the probe
OFF
There is no delay when material leaves the probe
The duration of the delay is determined by SW4 in conjunction with SW5-5. When active, SW5-5 multiplies the
delay by a factor of 5. The functionality of each switch is shown in the tables below.
