Cycle Time will need to be set for your specific system The Cycle Time is the amount of time in between samples when the blowdown valve is shut While the blowdown valve is shut the conductivity will rise in the boiler If the cycle time is too long the conductivity will rise much higher than the setpoint and this could cause problems for the boiler Conversely if the cycle time is set too short the conductivity will never raise high enough to hit the setpoint This will result is a waste of heat and water because the controller is blowing down when it is not necessary Once the Sample Time is set it should never have to be adjusted again The Cycle Time is the one that will need to be adjusted to the specifics of the application If the steaming load or the make up water quality changes the cycle time may need to be adjusted If the conductivity is always too low the cycle time should be set to a longer period of time If the conductivity is always too high the cycle time should be set to a shorter period of time The set up of a relay for the sample cycle method of conductivity control involves a 6 step process 1 Select the relay you wish to configure as a SAMPLE CYCLE relay 2 Select the boiler conductivity that the relay will be based on 3 Set the setpoint and deadband 4 Set the timeout function 5 Set the sample and cycle times 6 Set the ball valve delay When SAMPLE CYCLE is selected in the Relay Options screen a screen will appea
