Control Room Environment:This section describes environmental conditions of the control room to operate the system safely, and stably over a long period of time. It is recommended that user have the control room environment assessment. Consult Yokogawa sales for the assessment if necessary. n Temperatures and Humidity When equipment is brought from the place out of operational temperature range to the place in operational temperature range, bring it without a package, keep it within temperature change rate and avoid condensation. Keep ambient temperature within operational temperature range and leave it for more than three hours before starting operation. Under normal operation, the rate of change of ambient temperatures should be within 10 °C/h. All the equipment should be kept out of direct sunlight. |
Power Supply System:Voltage and frequency fluctuations are within the limits specified for each ystem component. •Relationship betweenthe waveform’s effective values and peak value is within the specified range. |
AC Power Specification :AC power used for the system must satisfied rated voltage and the peak value must be greater than the minimum specified (see below). DC power must satisfied 24 V DC at the power supply terminals. |
| Selecting a Power System： The CENTUM VP system requires a power supply that satisfies power requirements in accordance with EMC regulations. It is recommended that an external power supply unit is employed in order to prevent disruptions due to momentary or extended power failure, line noise, or lightening surges, as well as to suppress harmonic current from various devices. For selection of the power supply unit, consult with a power unit manufacturer taking the following points into consideration. |

YOKOGAWA MRI-234 B Overview
Overview |
The output board UTK-2 is used for controlling external relays, e.g. for fans and fire doors. The UTK-2 board is controlled by the alarm processor board LPK-2, via the address and data buses in the back plane. The UTK-2 board is equipped with 24 opto-isolated outputs for 24 VDC/50 mA. The outputs are divided into six groups where each group includes four outputs and a common positive conductor. The DC/DC circuit converts the battery voltage of the back plane to 5 VDC, which is supplied to all logical circuits on the board. Should the voltage disappear, a signal is activated in the back-plane. The battery voltage is fused. If the fuse is blown a signal is activated in the back-plane. The fuse is accessible on the front panel of the board, and can be used for disconnecting the power. On the front panel are two green LEDs for indicating 5V power and normal polling. The address bus, the data bus and the control signals are buffered before entering the board. The value written to the outputs can be read, to check the function of the board. The output latches also functions as drive circuits for the opto switches. s The outputs are divided into six groups, where each group has a common positive conductor. The load is connected between the output and ground. Each output is protected by a varistor and a freewheel diode for inductive loads. |
