1.0 Introduction
The CP-10 Control Unit can monitor one channel of gas detection when connected to a Sensor Transmitter(S/T). The CP-10
is NOT in an enclosure rated for use in a Class I, Div 1, Groups B, C, D classified area and can not be installed in a hazardous
location.
Features of the CP-10:
continuous monitoring of the target gas
continuous LCD display of gas and vapor concentrations
menu driven operational and maintenance controls
audio and visual alarms indicate unsafe conditions
alarm relay contacts available on terminals
a fault relay and visual fault alarm
alarm acknowledgement capability including audio defeat
mA outputs for target gas
N
OTE
: All specifications stated in this manual may change without notice.
1.1 Unpack
Unpack the CP-10 and examine it for shipping damage. If such damage is observed, notify both ENMET customer service
personnel and the commercial carrier involved immediately.
Regarding Damaged Shipments
N
OTE
: It is your responsibility to follow these instructions. If they are not followed, the carrier will not honor
any claims for damage.
This shipment was carefully inspected, verified and properly packaged at our company and delivered to the carrier in
good condition.
When it was picked up by the carrier at ENMET, it legally became your company’s property.
If your shipment arrives damaged:
• Keep the items, packing material, and carton “As Is.” Within 5 days of receipt, notify the carrier’s local office and
request immediate inspection of the carton and the contents.
• After the inspection and after you have received written acknowledgment of the damage from the carrier, contact
ENMET Customer Service for return authorization and further instructions. Have your Purchase Order and Sales

: 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.

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 S

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:

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 S
ELECT
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.
