1/8 DIN sized Manual Setter has large PV display, and transmit 4 to 20 mA DC signal by manual operation. It can be used as a remote setter of target setpoint for digital Indicating controllers. Two alarm outputs and PV retransmission output are standard features.

When I set up alarm values the parameters are initialized and I can't enter the settings.

(ns-faq-green-9071-setting)

Set them in the order, Alarm type → Alarm setting values. They will also not be displayed if you select an alarm for which no value is set.

What are energize/de-energize alarms?

(ns-faq-green-9076-term)

For energize alarms, ON contact results when an alarm occurs. For de-energize alarms, OFF contact results when an alarm occurs. Note that OFF contact also results when the power fails.

Is there a function for resetting alarms?

(ns-faq-green-9075-spec)

No. When an alarm occurs, it automatically recovers if values enter the normal range.

What should I do when b.out is displayed?

(ns-faq-green-9080-spec)

The sensor wire on the input side might be broken or disconnected.

Are contacts still good during malfunction?

(ns-faq-green-9081-spec)

There are 2 types of output available, FAIL and "failure diagnosis."

Please provide information about PCB usage. (GREEN series)

(ns-faq-green-9125-spec)

PCBs (polychlorinated biphenyl) were banned from manufacturing and imports in 1975. The GREEN series began to be manufactured in 1997, and do not include PCBs.

There is no indication on the display in the GREEN series.

(ns-faq-green-9082-spec)

Check whether the wiring to the power supply terminal is correct. If only the LCD on the UT/UP700 does not display, a custom computation may be set for no display. If the PV display is also blank, this may indicate product failure. Please contact you...

Can I write the PV value via communication?

(ns-faq-green-9048-spec)

The PV value can be written by using the ladder sequence function of UTAdvanced series. However, when communication is interrupted, the PV value is retained.

How do I change the input type?

(ns-faq-green-9014-spec)

If you change the input type, parameters will be initialized. We do not recommend that you make changes while in operation.

Do Green series controllers support Ethernet?

(ns-faq-green-9009-connect)

Yes. This requires an RS-485/Ethernet converter such as VJET. The controller must also have a communication option. Some models can be connected directly with the UTAdvanced series.
