3.2.1 Outputs

Two types of alarm outputs are available, relay contacts and 4-20mA outputs.

3.2.2 ISA-60M Relay Contacts

Relay contacts are available for each alarm; these are SPDT, rated at 10Amp at 110VAC or 10Amp at 30VDC for restive loads, and may be latching or non-latching as required by the application. They are accessed on the terminals next to each relay see Figure 2 & 5. The contact positions are noted on the circuit board next to each terminal.

These relay coils are energized when they are in the non-alarm state; the contact conditions given above are for the nonenergized state, which is identical to the alarm state.

In addition, there is a fault relay, which changes state whenever the instrument is in a fault condition. The contact positions are noted on the circuit board next to each terminal. The coil of this relay is energized when the instrument is in the non-fault state; the contact conditions given on the circuit board next to the terminal, are for the non-energized state, which is identical to the fault state.

The PC Board is labeled for the relays in their un-energized state. If the relay is configured for failsafe, then this is also the alarm condition state. Non-failsafe configured relays in the alarm state, are the reverse of the PC board labeling. Note that the Fault(FLT) relay cannot be set to operate in a Non-Failsafe mode. Please see the Table 2 below:

These relay contacts can be used to operate auxiliary alarms or other functions.

3.2.3 4-20mA Outputs

Isolated 4-20 mA outputs are available for data logging or other purposes. An output is supplied for each sensor supplied in a particular instrument, and can be added when a sensor is added in the field. These outputs are available on the Connector 1(J7) for channels 1 & 2 and Connector 2(J4) for channels 3 & 4.

4mA corresponds to the sensor reading of 0 at the bottom of the range. 20mA corresponds to a full scale reading of 30. Wiring requirements are the same as for the relays.

3.2.4 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.

3.3 Power Supply

The input power can vary from 100 to 240VAC, 50/60 Hz. Mains power should be connected to the Power Input Terminal J23 and the ground screw J21. See Figure 5 for location.

ARNING

Continuous gas detection and alarm systems become inoperative upon loss of primary power.

Upon supplying power to the ISA-60M:

 The green power on LED is lit.  The display backlight is lit, and instrument will step through a start-up sequence: unit serial number, software revision

and gases monitored may be shown on the display.

The instrument may go into alarm briefly, but the sensors stabilize quickly. If the instrument persists in alarm, acknowledge the alarm by pressing the A

UDIO DEFEAT /ALARM ACKNOWLEDGE

switch. If alarm persists longer than 30 minutes, call ENMET

customer service personnel. Mains power line is fused for power supply protection. Fuse is 5 x 20mm, 0.630Amp is located in FH2, see Figure 5

3.5 Initial Calibration

All instruments are calibrated at the factory. You may, if a calibration kit is available, calibrate the MRI-5175 3 – 4 hours after installation. See Section 5.0, Maintenance, for calibration instructions.

ISA-60M ENMET Corporation

O2 20.9

4.0 Operation

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.

Example of display

Figure 6: ISA-60M Operational Display

4.2 Alarm Set Points

There are two alarm set points for each active oxygen channel. They are adjustable from 16.0 to 24.9. The standard factory settings of these alarm set points are:

Alarm 1 is 19.5 % by volume, indicated by Flashing LED and audio alarm. Alarm 2 is 17 % by volume, indicated by Steady LED and alarm 1 LED changes from flashing to steady.

These alarm set points can be changed within limits; see the maintenance section of this manual for the procedure.  If the oxygen content of the sample air decreases below an alarm set point, the associated red LED activates, the associated

relay changes state, and the audio alarm is activated.

Differential Setting (Non Factory)

Differential is an optional alarm relay configuration where when an alarm has been triggered, the relay will remain in alarm state until the sensor reading has moved the differential “value” in the non-alarm direction. See example below.

 The Alarm 1 differential value is the delay of the ISA-60M staying in alarm condition until after the measured reading has

returned past the alarm point by the differential value. Example: If the alarm point is V 19.5 and the differential is 2, the ISA-60M will go into alarm at 19.5 and stay in alarm until the reading has risen above 19.7.

AUTION

: Setting the alarm points to the differential setting disables the audio alarm for alarm point 1. The differential Setting

has no effect on alarm relays or on the audio alarm for alarm point 2.

4.3 Fault Indications

Fault indications are associated with sensor zero and calibration activities, and are described in the maintenance section 5.0 of this manual.

4.4 Alarm Latching

An instrument is shipped with the alarms in the latching mode. The alarms may be independently configured in the nonlatching mode or differential setting by use of the maintenance menu. See Section 5.2.2, for setting alarm 1 and alarm 2.

An alarm can also be acknowledged by pressing the switch during the alarm condition; then at the cessation of the alarm condition, alarm indications cease and alarm relays revert to the non-alarm state. After an alarm is acknowledged, alarms in the latching configuration are re-armed to latch at the next alarm condition.

4.5 Audio Defeat

Pressing the 60M not on the MRI-5175. Relays and alarm LEDs continue to function, in the alarm state, during an alarm condition. As long as the alarm condition persists, the audio alarm will “chirp” every 20 seconds. After the alarm condition clears, the audio will continue to “chirp” until the audio switch is pressed.

 If after 15 minutes the alarm condition continues the audio alarm will reactivate at full intensity.  If any other alarm condition occurs while the audio alarm has been silenced it will force the audio alarm to reactivate

immediately.

5.0 Maintenance

The ISA-60M has no specific preventative maintenance requirements. Entering the maintenance menu, as outlined in Section

5.2 may change instrument configurations.

The MRI-5175 sensor will require periodic calibration and replacement. Oxygen sensor calibration should be preformed on at least a quarterly basis. The sensor has an estimated lifetime of 5 years. The sensor should be replaced when it will not calibrate or shortly before the 5 year time frame, to ensure continuous instrument operation. Sensor calibration instructions can be found in Section 6.0.

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.

5.2.2 MRI-5175 Calibration

Calibration is performed at the MRI-5175 remote sensor/transmitter. Calibration is the process of setting the instrument up to read accurately when exposed to a target gas. Wait at least 3 – 4 hours after initially supplying power to the MRI-5175 sensor/transmitter before calibration, Overnight

stabilization is preferred before calibration. The MRI-5175 has been pre-calibrated at the factory, and initial field calibration should result in only fine tuning the circuit, as well as a way to check that installation is successful. It is not necessary to open the enclosure to make adjustment. The calibration functions are operated through the for Power/Fault LED Sequence codes and Figure 9 Calibration MRI-5175.

switches. See Table 5

5.2.3 Standard Calibration

The following procedure is suitable for altitudes below 4500 ft (1372 meters):

1. Press and hold the Menu switch for 3 to 5 seconds, the Power /Fault led will flash red- green, red- green, red- green….

2. Assemble the cylinder flow regulator and MRI calibration adapter. To calibrate:

3. Press and release the Menu switch, then press and release the Select switch. This places the transmitter into the calibration Span operation. The Power/ Fault led will flash Green-red-red-red, Green-red-red-red…

4. Attach the MRI calibration adaptor, part number 03620-021 to the sensor, then pull the trigger on the cylinder of 20.9% Oxygen part number 03100-029 and partially inflate the bellows.

5. The MRI-5175 transmitter begins to look for signal stabilization; this process lasts from 60 to 120 seconds. Observe the Power/ Fault led during this time. When the signal has stabilized, the Power/Fault led will show green for 3 seconds, indicating a successful calibration, and then flash red-green, red-green… If the calibration was unsuccessful, following the 60 to 120 second stabilization time the Power/Fault led will show Red for 3 seconds and then flash red-green, red-green, red-green…

6. Press and release the Select switch to exit calibration and return to operation mode. If the calibration was completed successfully the Power/Fault led will show steady Green. If the calibration Failed the Power/Fault led will flash a Slow redgreen, red-green… Continue to flow the 20.9 Oxygen. Go to Section 5.2.5

5.2.4 Altitude Calibration

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.

1. Press and hold the Menu switch for 3 to 5 seconds, the Power /Fault led will flash red- green, red- green, red- green…

2. Assemble the cylinder flow regulator and MRI calibration adapter.

To calibrate:

3. Press and hold the Menu switch for 3 to 5 seconds, the Power /Fault led will flash red, red, red, red …

4. Press and release the Menu switch then press and release the Select switch. This places the transmitter into the calibration Span operation. The Power/ Fault led will flash Green-red-red-red, Green-red-red-red…

5. Attach the MRI calibration adaptor to the sensor, then pull the trigger on the cylinder and partially inflate the bellows.

6. The MRI-5175 transmitter begins to look for signal stabilization; this process lasts from 60 to 120 seconds. Observe the Power/ Fault led during this time. When the signal has stabilized, the Power/Fault led will show green for 3 seconds, indicating a successful calibration, and then flash red-green, red-green and then red, red, red… If the calibration was unsuccessful, following the 60 to 120 second stabilization time the Power/Fault led will show Red for 3 seconds and then flash red-green, red-green, red-green…

7. Press and release the Select switch to exit calibration and return to operation mode. If the calibration was completed successfully the Power/Fault led will show steady Green. If the calibration Failed the Power/Fault led will flash a Slow redgreen, red-green… Continue to flow the 20.9 Oxygen Go to Section 5.2.5

NOTE: After the initial Altitude Calibration, subsequent calibrations should be done following the Standard Calibration procedure.

6.0 Maintenance MRI-5175

The MRI-5175 sensor will require periodic calibration and replacement. Oxygen sensor calibration should be preformed quarterly, but not less than annually. The sensor has an estimated lifetime of 5 years. The sensor should be replaced when it will not calibrate or shortly before the 5 year time frame, to ensure continuous instrument operation.

6.1 MRI-5175 Calibration

Calibration is performed at the MRI-5175 remote sensor/transmitter. Calibration is the process of setting the instrument up to read accurately when exposed to a target gas. Initial Calibration: Wait at least 3 – 4 hours after initially supplying power to the MRI-5175 sensor/transmitter before initial

calibration, Overnight stabilization is preferred before calibration. The sensor has been pre-calibrated at the factory, and initial field calibration should result in only fine tuning the circuit, as well as a way to check that installation is successful. It is not necessary to open the enclosure to make adjustment. The calibration functions are operated through the switches. See Table 5 for Power/Fault LED Sequence codes.

ENMET Corporation recommends quarterly, but not less than annual, calibration of the MRI-5175 transmitters.
