    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.

    : 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.

  • Page 20: Failsafe Configuration

    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.
