3.0 Installation of the CP-10
The CP-10 is supplied with a strain relief for a power line cord. Use this fitting or connect a conduit fitting when supplying
power to the unit.
NOTE:This control panel is NOT rated for hazardous locations. The control panel must be located in a NON-Hazardous area.
3.1 Mounting CP-10
Mount the CP-10 instrument on an appropriate vertical surface, leaving room for lid to be opened, using the mounting holes
provided. Avoid areas with excessive vibration or temperature extremes. The holes in the bottom of the enclosure are 0.18
inch in diameter and form a 6.44″x 4.47″rectangle. See Figure 3
It is recommended to use #8 drywall anchors and screws for mounting the CP-10 to a drywall/sheetrock surface.
Dimensions are in inches.

3.1.1 Wiring the CP-10
The electrical installation should conform to appropriate electrical codes, such as the National Electrical Code in the United
States.
W ARNING : The compliance of the installation to appropriate codes is not ENMET’s responsibility.
The CP-10 should be powered through appropriately sized circuit breakers. See Section 6.0 Technical Data.
3.1.2 Power Supply
The input power can vary from 100 to 240 VAC, 50/60 Hz. Power should be connected to the Power Input Terminal TB1 and
the Ground screw. See Figure 4 for location.
For DC wiring 24VDC may be wired to J12, (J12-1)position 1 + with ground connected to (J12-2)position 2.
Upon supplying power to the CP-10:
The green power on LED is lit.
The display backlight is lit, and instrument will step through a start-up sequence: unit serial number and software revision
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 SELECT button. If alarm persists longer than 30 minutes, call ENMET customer service personnel.
W ARNING : Continuous gas detection and alarm systems (110VAC/220VAC / 24VDC/12VDC powered) become inoperative
upon loss of primary power. Contact factory for specifications and pricing of backup battery systems.

Gases have different densities. Some are heavier than air and concentrate at the bottom of a space. Some are lighter than air
and gather at the top. Consider the density of the gas you want the sensor to detect when you install the sensor. Some
examples are given below.

3.3 Relay Contacts
Relay contacts are available for each alarm; these are SPDT, rated at 10Amp at 110VAC, and may be latching or non-latching
as required by the application.
They are accessed on the terminals next to each relay see Figure 5. The contact positions are noted on the circuit board next to
each terminal.
The following table is for the relays in their un-energized state. 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 Table 1 below:

These relay contacts can be used to operate auxiliary alarms or other functions. The relay contacts are DRY, power must be
supplied. It is recommended that power for auxiliary equipment be supplied from an independent power source separate form
the CP-10. Use the existing hole in the enclosure for wire to enter and exit and use appropriate cable fittings. Wiring should
be grouped together, VAC wires should be separated for VDC wires.

4.0 Operation
When the CP-10 is 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 measurement of the target detected by the CP-10.The red alarm and fault LEDs are not lit.
4.1 Start Up CP-10
When the CP-10 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. See the Section 4.1.1 below
4.1.1 Typical Start Up
When power is supplied to the CP-10, the instrument will display the following sequence of information:

4.2.1 Alarm Conditions CP-10
There are three 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 SELECT button can temporally disable the Audio Alarm. The horn will be disabled for 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.
