stable control is impossible. Therefore, digital filter function stabilizes current temperature value. For example, set input digital filter
value as 0.4 sec, and it applies digital filter to input values during 0.4 sec and displays these values. Current temperature may be
different by actual input value.
SSR drive output method (SSRP function)[SSrM]
SSRP function is selectable one of standard ON/OFF control, cycle control, phase control by utilizing standard SSR drive
output.
This function parameter appears only in SSR drive output model (TX4 – 4S).
Realizing high accuracy and cost effective temperature control with both current output (4-20mA) and linear output(cycle control
and phase control)
Select one of standard ON/OFF control [STND], cycle control [CYCL] , phase control [PHAS] at SSrM parameter of parameter 2
group. For cycle control, connect a zero cross turn-on SSR or random turn-on SSR. For phase control, connect random turn-on
SSR.
When selecting cycle or phase control mode, the power supply for a load and a temperature controller must be the same. Control
cycle[T] is able to set only when control method[C-MD]of parameter group 2 is set as PID and SSR drive output method [SSrM] is set
as STND In case of selectable current output or SSR drive output model(TX4 – 4C), this parameter does not appear. Standard
ON/OFF control by SSR is only available.
1. Standard ON/OFF control [STND] Controls ON (100% output)/OFF (0% output) as same as standard relay output.
2. Cycle control [CYCL] Controls the load by repeating output ON / OFF according to the rate of output within setting cycle based
on certain period (50-cycle). Control accuracy is almost the same with phase control’s. This control has improved ON/ OFF
noise than phase control’s due to zero cross type which turns ON/OFF at zero point of AC.
3. Phase control [PHAS] Controls the load by controlling the phase within AC half cycle.Serial control is available. Must use
random turn-on SSR for this mode.
