CCM Series - Current Switch Clamped Mini

Model CCMF015

Installation Instructions

Introduction

The Current Switch Clamped Mini (CCM) Series of digital
output switches are noninvasive devices designed to detect
low current flowing through a cable or wire. A cost effective
solution for monitoring on and off status or proof of operation,
these units are ideal for monitoring small current loads on
motors driving fans and blowers, and for sensing the status of
heating coils and lighting.

These units provide a universal solid state output and do not
require a power supply. Excitation is magnetically induced
from current carrying conductor (wire or cable), making these
units completely self-powered.

IMPORTANT: The Current Switch Clamped Mini (CCM) Series Current
Devices are intended to provide an input to equipment under normal
operating conditions. Where failure or malfunction of the CCM could
lead to personal injury or property damage to the controlled equip­ment or other property, additional precautions must be designed into
the control system. Incorporate and maintain other devices such as
supervisory or alarm systems or safety, or limit controls intended to
warn of, or protect against, failure or malfunction of the CCM.

Installation

WARNING: Risk of Electric Shock

Disconnect power supply before making elec trical con-

!

nections. Contact with components carr ying hazardous
voltage can cause electric shock and may result in
severe personal injury or death.

Dimensions

42.9 (1.69)

43.7 (1.72)

21.1 (0.83)

Mounting

1. Using the two screws (included), attach the mounting
bracket to the back of the electrical enclosure.

2. Snap the CCM into place on the mounting bracket.

Wiring

1. Disconnect power to the conductor cable from the power
source.

2. Snap the split core around the power conductor cable,
and close the core until the core snaps shut.

Note: The switch contacts are solid state, and they work just
like dry contacts When the switch is closed, less than 1 ohm
is present; when the switch is open, more than 1 megohm
is present.

3. Wire CCM output terminals to the control box Digital

Input (DI) terminal (30 VAC/42 VDC max. terminal
voltage).

4. Reconnect the power conductor cable (For wiring

example, see Figures 2.)

CCM Series - Current Switch Clamped Mini Installation Instructions 1

If the measured current is too low to be detected or is higher
than the maximum current rating of the CCM, use the follow­ing methods to increase or decrease current.

If Measured Current is Too Low to be Detected

Wrap the conductor (wire) through the sensing hole
and around the CCM body to product multiple turns to
increase the measured current. Measured current =
actual current times the number of turns (see Figure 3).

Figure 3: CCM Shown with Four Turns

IMPORTANT: Failure to derate the current capacity could result in
damage to the CCM when using multiple turns to increase measured
current. Use the following formula to determine the new maximum
current:

New Maximum Current = CCM Current Rating/number of turns
For example, Model CCMF015 with 4 turns = 60 A/4 = 15 A, new
maximum current.

To Monitor Currents Exceeding the Maximum
Current Rating of the CCM

For currents >60 A (Model CCMF015)

Use a 5 A Current Transformer (CT ) to reduce the current

passing through the CCM as shown in Figure 4. Run the
current transformer secondary wire through the sensing
hole. Terminate the 2 secondary wires of the 5 A current
transformer to each other, and then install the

5 A current transformer on the monitored conductor.

Current>60 A

Troubleshooting

Table 1: Troubleshooting

Symptom Action

CCM solid state output does not function Verify the maximum amperage range has not been exceeded. Voltages or

currents above the rated levels may damage the CCM.

Motor is turned on and switch does not close Insufficient current to the load leads ( for example, a motor or heater) to reach

the setpoint threshold. To turn the switch on, wrap the cable multiple times
through the sensing hole (see Figure 3).
