The exterior and panel of the sensor/transmitter is shown in Figure 1. The MRI-5175 features are as follows: Feature Description Enclosure Fiberglass-reinforced polyester approximately 5” square, with non-magnetic hardware. Entrance for wiring to ISA-60M control unit Strain Relief Mounting Flanges Flanges with holes for mounting the enclosure to a vertical surface. MENU Switch...
The holes in the flanges are 0.31 inch in diameter and form a 6 x 10.75 inch rectangle. See Figure 3. It is recommended to use #8 drywall anchors and screws for mounting the ISA-60M to a drywall/sheetrock surface. Non-magnetic mounting hardware is required for control panels located in the magnet room.
See Figure 1. Follow state and local guidelines when selecting appropriate strain relief, conduit and wiring. Remote Sensor: Each must be connected to a 4-20mA input inside the ISA-60M. UL listed type CM, PLTC or TC cable shall shielded be used for wiring between the MRI-5175 and the ISA-60M control panel.
Wiring requirements are the same as for the relays. 3.4.4 Digital Outputs The RS232 & RS485 connections are used for firmware updates and digital communications. The ISA-60M is designed to operate as a modbus slave. Contact the ENMET for further information on wiring for the digital outputs.
4.1 Normal Operation Condition With the ISA-60M installed as described in Section 3, and in clean air, the POWER green LED is on, the display is lit, and the information on the display is as shown in Figure 6, for the sensor(s) installed in the ISA-60M. The red alarm and fault LEDs are not lit.

: Never spray a cleaning solution on the surfaces of the ISA-60M or MRI-5175 devices. AUTION Clean the exterior of the ISA-60M and MRI-5175 enclosures with a mild soap solution on a clean, damp cloth. Do not soak the cloth with solution so that moisture drips onto, or lingers on, external surfaces.
5.2.1 Set 4 –20mA Transmitter Scale This section of the maintenance menu is for aligning the external sensor/transmitters MRI-5175 to the ISA-60M controller. This function is normally performed at the factory and is not usually required in the field unless a new transmitter is installed.

ISA-60M ENMET Corporation 5.2.7 Set Alarm “Delay On” The alarms may be set to delay activation by 1 second increments. Factory set default value is 5 seconds. After entering a valid password: Press the OPTION switch until; “Maintenance Menu Set Alarm Delay” appears on display.
The ISA-60M is factory set in a failsafe configuration. This means that if power is disconnected to the unit, or the relay fails to properly engage, it fails in such a way that it is in the alarm position. ENMET recommends leaving the relay in a failsafe configuration.
: Deactivated channels will not display or respond to connected sensor transmitters. AUTION A fault indication occurs when a transmitter is not connected to an active channel of the ISA-60M. To Activate or deactivate a channel of the ISA-60M: Enter the maintenance menu as described in Section 5.2 and press the switch until Exit maint menu appears.
This procedure is required for altitudes above 4500 ft (1372 meters). Due to the reduction of partial pressure at elevations above 4500 ft (1372 meters), the following procedure must be used when installing the ISA-60M monitor. Subsequent calibration should be done using the Standard calibration procedure as the compensation for partial pressure variances will have been accomplished.
