3.21: Time-Based Outputs
(Available Only on Option P Units)
These outputs are programmed to turn on based on position and turn off based on a keypad selectable
time interval. Circuits one through six can be selected for this type of operation. Circuits cannot be
programmed for
Linear Speed Offset
and
Time-Based
outputs at the same time; thus the total
combined number of
Linear Speed Offset
and
Time-Based
outputs cannot exceed six.
NOTE:
CIR# 301 thru 306 only enable the circuit so that it can be programmed for a
Time-Based
output. After
Time-Based
circuits are enabled, see Section 3.8: Setpoints.
The
Time-Based
feature is programmed as follows:
A)
Unit must be in the Program mode.
B)
Depress
CIR# 301 represents CIR# 1, CIR# 302 represents CIR# 2, etc. A zero (0) after CIR# 301-
306 means that the circuit will function as a normal limit switch as outlined in Section 3.8:
Setpoints; however, if a one (1) is entered in after CIR# 301-306, it means that the circuit is to
be set up for a position ON and a timed OFF output.
C)
This sequence only enables or disables LS1 thru LS6 for
Time-Based
operation. After an LS
is enabled as a
Time-Based
circuit, follow normal programming instructions. See Section 3.8:
Setpoints, C and D.

NOTE:
If LS6 is set as a motion detector, it cannot be set for
Time-Based
.
D)
A
Time-Based
output may only have one CIR ON and one CIR OFF setpoint. This output
will turn on based upon the CIR ON position data and will turn OFF based upon the CIR OFF
time data, which is displayed and programmed in 0.01 second increments. A
Time-Based
output uses three setpoints. See Section 3.7: Setpoint Formula.
E)
Outputs 1 through 6 may incorporate
Linear Speed Offset
or may be
Time-Based
. How
ever, no output can be both. In addition, LS6 may be selected to be a motion detect output. If
two or three types of outputs are required, first select the number of
Linear Speed
circuits
required (CIR 80) and then individually select the
Time-Based
outputs and
Motion Detect
output.
Example:
Outputs 1 & 2
Linear Speed
CIR = 80 - ENT - 2 - ENT
Outputs 3 & 4
Time-Based
CIR = 303 - ENT - 1 - ENT
CIR = 304 - ENT - 1 - ENT
Output 6
Motion Detect
CIR = 55 - ENT - 1 - ENT
