About this manual

RLY00765, the Trane Motor Protection Module (also called the Electronic Overload,
A1), is no longer available.

KIT09437 is a functional replacement utilizing components used with Tracer CH531
control systems. It is not a complete CH531 controls package installation. It does not
provide distribution fault protection. As configured this kit does not provide
momentary power loss. It can provide phase loss and phase rotation protection along
with standard motor protection features relating to currents and load. This kit will
measure motor currents and provide an analog output to be used as input for existing
temperature control device like the MOD00182.

To properly install this replacement, the technician must have a good, working
knowledge of Tracer CH530 or CH531 control systems.

Three (3) new current transformers (CTs) are required to complete this installation.
They are not included in this kit. They must be ordered separately based on unit RLA.
See Table C4 or C5 in Appendix C for CT sizing details and part numbers.

Installation

Removal of Components

 WARNING
Hazardous Voltage!

Disconnect all electric power, including remote disconnects before
servicing. Follow proper lockout/tagout procedures to ensure the
power can not be inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.

It is assumed that all work can be done inside the starter panel. No wiring should
have to be done in the control panel. However, access to the control panel to verify
wiring origins may be necessary.

Removal of Motor Protection Module (A1 or MPM), and Circuit Breakers CB11 and
CB15

1. Before removing the MPM, mark wires landing on V1, V2, D1 (wire #125B) & D2
(wire #127A). These wires will be re-landed on CH531 components.

2. Remove wires from CTs that land on C1-C6. The existing CTs can be removed
and discarded. New CTs will be used with CH531 components. The new CTs are
not included in this KIT. They must be ordered separately. See Table 1 in Appendix
C for details.

3. Remove wires (#130 and #131) for CB11 (Compressor Motor Current Overload)
from F1 and F2. Remove wires (#132 and #133) for CB15 (Distribution Fault) from
E3 and E4. These two circuit breakers, CB11 and CB15, in the starter panel door
will have to be removed as they will no longer be required, the functions will be
performed by the CH531 components.

See Appendix B for wiring details.

A sheet of black vinyl is included so that “patches” may be cut to fit and be placed
over the holes in the starter door where these breakers were mounted.

The Starter Circuit Fault Indicator (CB13) can remain as wired.

Remove the remaining wires from the MPM and remove the module.

When complete the bottom bracket should be left attached to the starter backpanel.
The new component sub-panel sent in this kit will attach to the tapped holes on the
flanges of the existing bottom bracket.

Wiring from backpanel components to starter components

Wiring from the terminal block and starter module can be run to various existing
starter terminals. The terminal numbers used for the starter panel assume a Trane­provided, unit-mounted wye-delta starter. Other starter types may use different
terminal numbering. See Appendix A for a copy of existing wiring diagrams used for
this replacement.

The Starter Module will not control the entire starting process. The original sequence
of events of the existing starter will be preserved. The starter module will initiate the
start signal, provide a transition signal (for wye-delta starters), and monitor motor
currents just as the MPM did. CH531 requires a “transition complete” signal back
from the starter, which the MPM did not.

CT meter scale setting

The CT Meter Scale is an especially critical factor and must be calculated correctly.
One of two methods of calculation should be used. Typically applications of less than
600 Vac will have a single stage CT per phase connected to the starter module.
Likewise, medium voltage applications greater than 600 Vac have a two stage CT
per phase connection to the starter module. Select the correct method for this
application from the two choices that follow.

Method 1. Single stage CT calculations, less than 600 Vac only

Motor current sensing using the single stage CT per phase arrangement. In this case
only one CT is used per phase to achieve the necessary turn-down ratio of current
measurement. The CT consists of either the X13580253 or X13580269 part. This CT
reduces the 100% RLA signal input to a nominal 100 mA value for input to the
starter module.

CT Meter Scale = CT Rating / (Number of Primary Turns x 1.00)

CT Meter Scales with decimals need to be truncated as appropriate so that the
measured motor amps is less than the actual motor amps.

23 PART-SVN82C-EN

See Table C4 to select CT Rating and resulting CT meter scale. In many cases more
than one selection is possible.

Method 2. Dual stage CT calculations, for greater than 600 Vac

Motor current sensing using the two CT per phase arrangement. In this case two
CT's are used per phase to either achieve the necessary turn-down or for metering
convenience. The first stage consists of either the X13580047 or X13580048 CT
(each of these CT's have a 5 amp secondary). The second stage consists of the
X13580266-01 CT (takes 3.6 amps down to 100 ma).

CT Meter Scale = CT Rating / (Number of Primary Turns x 1.3889)

CT Meter Scales with decimals need to be truncated as appropriate so that the
measured motor amps is less than the actual motor amps.

In this case the CT Rating should be picked to be in the range of 100% to 150% of
Actual Motor RLA x Number of Primary Turns x 1.3889. See Table C5 to select CT
Rating and resulting CT meter scale. In many cases more than one selection is
possible.

Additional CT equations

There are a number of equations and constraints that are used with CT selection.
This section addresses these and their definitions.

First the definitions:

1. On a dual stage CT system, CT1 is the primary winding rating of the first stage
(or line) CT with respect to the 5 amp secondary. For example, a first stage CT
rating of 500:5 has a CT1 of 500.

2. On a dual stage CT system, CT2 is the primary winding rating of the second
stage CT with respect to a 100 mA secondary. For example, a second stage CT
of rating 3.6:0.1 has a CT2 of 3.6.

3. TVCTMS is the CT Meter Scale entered into TechView

4. TVRLA is the RLA entered into TV in amps.

5. Act %RLA is the actual %RLA the motor is drawing

6. Act RLA is the actual Running Load Amperage of the motor

25 PART-SVN82C-EN

Appendix C

7. NT1 is the number of primary turns on CT1

8. The current as displayed in TechView and DynaView is determined by the follow­ing equation:

TVCTMS

RLAMeasured

9. The ratio of CTMS/RLA must meet the following:

If CTMS/Motor Rated Load Amps is not in this range, then the ratio CTMS/Motor
Rated Load Amps = 1.5 shall be used. Note that the limits on CTMS/RLA is 0.8 and

1.5 in the TechView product data base. However the Starter module limits this ratio

to the 0.87 and 1.63.

10. To ensure that the proper current overload is in place, CT1 should be

chosen such that:

Binding view

The following figure shows the binding view screen for this installation. Note that
the LLIDs that show up on this list are dependent on selections made in previously
in Configuration View.

Initially, the LLIDs will show up as Red frowning faces indicating they are unbound.
Binding is a process by which a particular LLID is assigned to monitor or control a
particular function or item.

Select the LLID to be bound, click on the Bind button in the task bar. A window will
pop up asking “Particular LLID. Is the desired device alone selected?” Locate the
LLID in the control panel or starter and place the Trane provided magnetic
screwdriver near the LED under the SW1 arrow. The green LED will turn on. Click
“YES” on the pop up window. The smile face will turn green next to that LLID on the
binding view menu.

Continue for all LLIDs in the list.
