Old Id.Nr.: 149674
Wiring diagram
Product description
The ST501-JX1TA controller comprises a control unit and a power supply unit board. Both com-
ponents are interconnected via a ribbon cable and form a plug-in unit. All input and output connec-
tions are established in the rear on the power supply unit board. The unit provides the functionality
of a temperature controller for fan drawers.
A triac for fan control and a relay are provided as outputs. The relay is a normally open contact and
can be defined either as control circuit 2 or as an alarm contact using the parameter setting function.

- Page 3 SOFTWARE for fan control Adjustment options UP key Press this key to increment the parameter number or parameter value. DOWN key Press this key to decrement the parameter number or parameter value. In the event of an alarm, the buzzer is silenced by pressing this key. SET key The setpoint is displayed while this key is pressed.
- Page 4 Second control level (P parameters): Setting of control parameters Press and hold the UP and DOWN keys simultaneously for at least 4 seconds to access a parameter list containing control parameters. Press the UP key to scroll up in the list and the DOWN key to scroll down in the list.
- Page 5 Parameter description: P1: Setpoint 2 / delta W The second setpoint affects control circuit 2 and can be adjusted in 2 variants (see parameter A5 for selection): First controller variant (cf. figure 1): Second controller variant (cf. figure 2): Contacts K1 and K2 are linked via switching Contacts K1 and K2 can be adjusted difference delta W (operation with delta W).
- Page 6 P8: Reset time Tn, I-portion The proportional controller as such has a remaining deviation of the actual value from the setpoint. The integral portion provides for a complete compensation of this offset. The reset time is a measure for the period of time needed to adjust a remaining temperature deviation of the size of the proportional range.
- Page 7 P32: Hysteresis, alarm contact The hysteresis is to one side of the limit. In the case of the limit alarm, the hysteresis works upward from the lower limit and downward from the upper limit. In the case of the range alarm, the hystereses work in the opposite directions, i.e.

- Page 9 Parameter description: The following values may change the equipment characteristics and are therefore to be set with the utmost care: A1: Fan controller mode A2: Control circuit 2 mode The controller mode (cooling or heating function) can be individually programmed for the two control circuits at the factory.
- Page 10 A52: Minimum action time for control circuit 2 “On” A53: Minimum action time for control circuit 2 “Off” These parameters can be used to delay activation/deactivation of the output contact in order to reduce the frequency of switching operations. The minimum action time defines the entire minimum duration of a switch-on or switch-off phase.
