3.20: Time-Based Outputs
(Available Only on Option “P” Units)
NOTE: CIR# 301 thru 305 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-
305 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# 301-305, 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 LS5 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.
CIR# - (301 thru 305) - (0 or 1) - - ENT ENT .
NOTE: If LS5 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 5 may incorporate Linear Speed Offset or may be Time-Based. How-
ever, no output can be both. In addition, LS5 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
In instances where it is desirable to have an output actuate based on crank position and turn off based
on time, we offer time-based limits. Examples of areas where time-based limits are applicable include
lubricators and air blow-off limits. Even if the press stopped in the limit “dwell” area, it would only stay
energized for a specific time period, eliminating potential waste. Circuits one through five 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 five.
Outputs 3 & 4 Time-Based
CIR = 303 - ENT - 1 - ENT
CIR = 304 - ENT - 1 - ENT
Output 5 Motion Detect
CIR = 55 - ENT - 1 - ENT
