3.3 Power Supply

The electrical installation should conform to appropriate electrical codes, such as the National Electrical Code in the United States.

ARNING

The compliance of the installation to appropriate codes is not ENMET’s responsibility.

The CP-60 should be powered through appropriately sized circuit breakers. See Section 6.0 Technical Data. Upon supplying power to the CP-60:

 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 should stabilize quickly. If the instrument persists in alarm, acknowledge the alarm by pressing the A Sensor/Transmitter installation, 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

3.4.2 Relay Contacts

Auxiliary alarms should be powered from an independent power source separate form the instrument power to avoid alarm failure due to controller malfunction.

Relay 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 Figures 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 1 below:

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

3.4.3 4-20mA Outputs

Isolated 4-20 mA outputs are available for data logging or other purposes. An output is supplied for each active channel. These outputs are available on the Connector 1(J7) for channels 1 & 2 and Connector 2(J4) for channels 3.

4mA corresponds to the sensor reading of 0 at the bottom of the range. 20mA corresponds to a full scale reading. 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 CP-60 is designed to operate as a modbus slave. Contact the ENMET for further information on wiring for the digital outputs.

Figure 6: CP-60 Operational Display

When the CP-60 is first powered up, it goes through a series of momentary screens, which identify the instrument model number, serial number and software revision. After all of the momentary screens have been displayed, the instrument arrives at the Main Gas Display showing the gas concentration and unit of measurement in ppm, % or %LEL.

Depending on transmitter configuration and calibration condition, the furthest right character in the display may flash a letter indicating the instrument status.

4.2 Alarm Conditions

There are two alarm set points available. These alarm points are normally set at established safety levels, such as the OSHA Permissible Exposure Limit (PEL) for toxic gases or recognized standards below the Lower Explosive Limit for combustible gases.

These alarm set points can be changed within limits; see the maintenance section of this manual for the procedure. When the Oxygen, Toxic or combustible gas concentration reaches the alarm set point, the associated red LED is lit, the

associated relay changes state, and the audio alarm is activated Pressing the A

about five minutes. If a second alarm condition occurs during this time the horn will re-activate. If the alarm condition(s) have ended during this time, the horn will not re-activate.

Differential Setting

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 CP-60 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 CP-60 will go into alarm at 19.5 and stay in alarm until the reading has risen above 21.5.

4.3 Alarm Latching

Pressing the 60 not on the sensor/transmitter. 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.
