Model: UM330 Digital Indicator with Alarms


Descripción General:

Parameter sets of the Green Series controllers are loaded with factory input types including Thermocouples and 100Ω RTDs. Many industrial applications utilize a 10Ω Cu RTD as the temperature sensor of choice. This application note describes the setup and calibration for Green Series controllers for a 10Ω Cu RTD input.

These are used when 2-wire transmitters are used in the field. They provide cost savings since they do not need to be purchased separately. 24 V (21.6–28.0 VDC, 30 mA MAX) sensor power supplies can be specified with the following models: UT551,...
This is a function in which output occurs a specified time after an alarm set point is exceeded. If you clear the alarm point during operation of the timer, the timer is reset.
Can I perform CC-Link communication?
Yes, by using the UTAdvanced series.
Once input is set, IN is not displayed when you turn the power ON.
This function supplies power to 2-wire transmitters. It differs depending on the specifications of the transmitter, but the input accepts 100 Ω resistors. 100 Ω resistor (model: X010-100-2, sold seperately)
Sample programs and dedicated communication materials are available for MELSEC-A/MELSEC-Q.
Ladder communication is used when communicating with the Computer link unit/Serial communication unit. Modbus/RTU is used for communication with the Modbus communication module.
Almost all items can be accessed, including PV reading, SP writing, and PID setting.
This is a limit on the number of times you can write to the element used (EEP-ROM).
The common for all GREEN series alarm relay outputs are shared. In the UTAdvanced series, each alarm relay output has its own common. If used the same way, use external wiring to connect common to common.
Program changes for reading PV and OUT, writing SP, and other basic parameters are not necessary. There are registers and relays that support the GREEN series. For details see the UTAdvanced series communication interface (RS-485, Ethernet) user'...
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.
There is no current input range.
Use a resistor to input current as voltage. A resistor is available: X010-250-2 (250 Ω).
Do Green series controllers support Ethernet?
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.
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.
600 Ω.
Yes, but if you change some parameters, others will be initialized. We do not recommend that you make changes while in operation.
These cannot be set when in Custom Computation mode.
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...
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 are 2 types of output available, FAIL and "failure diagnosis."
No. When an alarm occurs, it automatically recovers if values enter the normal range.
The sensor wire on the input side might be broken or disconnected.
How do I change the input type?
If you change the input type, parameters will be initialized. We do not recommend that you make changes while in operation.
What are energize/de-energize alarms?
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.
The are set with a real number. For temperature, it is set in degrees Celsius.
Terminals 16(+) and 17(-).
