V1.00, August 30, 2004584.9.7 Time Set PointsThe time set points allow the user additional flexibility to activate events betweenspecific times. There are three time set points available.Time set points are useful to exercise a bank of fans periodically. For example,the user can set the device to pick up an output at 03:00 hours and drop out at04:00 hours. Time set points can be used in conjunction with the temperature setpoints to control an output. Therefore, when controlling a bank of fans for thepurpose of exercising them daily, it is necessary to OR (+) the temperature setpoint to the same output as the time set point. Time set points are by default,OR’ed to any other operand assigned to the same output.A counter is provided to set the frequency at which the time set points willoperate. For example, setting the counter to 7 will operate the time set pointsevery 7 th day.Time set points use a 24 hour clock.When using time set points in conjunction with temperature set points for thepurpose of picking up a cooling bank in fail-safe mode, both set points should beassigned as usual. To operate in fail-safe, apply the OUT INVERT to the specificoutput.4.9.7.1 Time Set Point SettingsTo set and assign the TSP1 (TIME1), TSP2 (TIME2), TSP3 (TIME3) to an outputfrom the front panel, press the %%%% or &&&&arrow buttons until the setting 082 isdisplayed:The first time, 00:00 is the pickup time. The second time, 00:00 is the drop outtime. OUT0 is the output the time set point is assigned to. In this case TSP1 isnot assigned.Press the YES button. The 10’s hour digit will flash. Use the %%%% or &&&&arrow buttonsto set this digit. Use the (((( button to move to the 1’s hour digit and observe thatit flashes. Again use the %%%% or &&&&arrow buttons to set this digit. Scroll to the 10’sminute digit by pressing the (((( button and observe that it flashes. Use the %%%% or&&&&arrow buttons to set this digit. Scroll to the 1’s minute digit and observe that itflashes. Use the %%%% or &&&&arrow buttons to set this digit. Scroll once more to theoutput number by pressing the (((( button. Use the %%%% or &&&&arrow buttons to set theoutput number from 0 to 4.PROGRAM TSP1 0820 0 : 0 0 - 0 0 : 0 0 > O U T 0
