  • Page 34: Alarm

    The controller has one alarm output. There are 6 alarm functions and one dwell timer that can be selected, and four kinds of alarm modes ( ALMD ) are available for each alarm function ( ALFN ). Besides the alarm output, the output 2 can also be configured as another alarm.

    Normal Alarm : ALMD = NORM Normal Alarm : ALMD = NORM When a normal alarm is selected, the alarm output is de-energized in the non-alarm condition and energized in an alarm condition. Latching Alarm : ALMD = L TCH Latching Alarm : ALMD = L TCH If a latching alarm is selected, once the alarm output is energized, it will remain unchanged even if the alarm condition is cleared.

  • Page 37: Dwell Timer

    Alarm output can be configured as dwell timer by selecting TIMR for ALFN . As the dwell timer is configured, the parameter SP3 is used for dwell time adjustment. The dwell time is measured in minutes, int the range of 0.1 to 4553.6. Once the process reaches the set point the dwell timer starts to time down to zero (time out).

  • Page 39: Digital Filter

    In certain application the process value is too unstable to be read. To improve this a programmable low pass filter incorporated in the controller can be used. This is a first order filter with time constant specified by parameter . The default value of FILT is 0.5 sec. before shipping.

  • Page 40: Failure Transfer

    The controller will enter as one of the following conditions occurs: occurs due to the input sensor break or input current below 1mA if 4-20 mA is selected or input voltage below 0.25V if 1-5 V is selected . occurs due to the A-D converter failure. Output 1 and output 2 will perform the function as the controller enters failure mode.

  • Page 41: Auto-Tuning

    1. The system has been installed normally. 2. Set the correct values for the setup menu of the unit. But don't use a zero value for PB and TI , otherwise, the auto-tuning program will be disabled. The LOCK parameter should be set at NONE.

  • Page 42: Manual Tuning

    The auto-tuning can be applied either as the process is warming up ( Cold Start ) or as the process has been in steady state ( Warm Start ). After the auto-tuning procedures are completed, the AT indicator will cease to flash and the unit revert to PID control by using its new PID values.

  • Page 46: Cool Only Control

    A TC 96 is used to control a refrigerator at temperature below 0 C. ° The temperature is lower than the ambient, a cooling action is required. Hence select DIRT for OUT1. Since output 1 is used to drive a magnetic contactor, O1TY selects RELY. A small temperature oscillation is tolerable, hence use ON-OFF control to reduce the over-all cost.
