Replacement kit for Hiquel TCP-M2, TCP-M2A and TCP-M2B.

The Hiquel TCP-M2 and its successors TCP-M2A and TCP-M2B are combined Phase Failure and Thermistor Motor

Over-temperature protection relays which were manufactured for many years for a UK based manufacturer of

Traction and Hydraulic Lift Electrical Control Panels.

Charter Controls was instrumental in the development of the TCP-M2 which was manufactured in Austria by Hiquel

Elektronic GmbH for our customer Liftstore, later Thames Valley Controls Limited (TVCL)

The TCP-M2/A/B is no longer manufactured but it is easy for a competent suitably qualified engineer to replace

using individual Phase Failure relays and Thermistor Motor Over-temperature relays. These do not have to be

supplied by Charter Controls however we recommend the two items in this kit.

DO NOT ATTEMPT THIS MODIFICATION UNLESS YOU ARE SUITABLY QUALIFIED. CHARTER CONTROLS, ITS OFFICERS

AND EMPLOYEES CANNOT BE HELD LIABLE FOR ANY DAMAGE, INJURY OR DEATH CAUSED BY INCORRECT FITTING.

This information is for guidance only and may not suit all TCP-M2, TCP-M2A & TCP-M2B installations.

The TCP-M2 was supplied from the three phases, which internally powered the Phase Failure function and the

Thermistor function. The MG21DH and MJ93BK have separate supply connections.

Phase Failure function

The GIC MG21DH 3-phase 3-wire Voltage Relay (Phase Failure Relay) will provide Phase Failure protection. It should

be set to measure the correct three-phase supply voltage using the rotary switch on the front plate

The Three-phase connections L1-L2-L3 on the TCP-M2 are connected to L1-L2-L3 on the MG21DH.

The alarm relay connections 15 (Common), 16 (NC), 18(NO) replace connections 11 (Common), 12(NC), 14(NO) on

the TCP-M2.

NOTE: After a Phase fault the MG21DH will auto-reset when the 3-phase supply voltage returns to normal. Check

the DIP Switch setting on your TCP-M2 and verify that this is acceptable.

Thermistor Motor Over-temperature function

The GIC MJ93BK PTC Thermistor Relay will provide Motor Over-temperature protection

It must be connected to a supply voltage between 220-440Vac

The Thermistor connections T1 and T2 on the TCP-M2 must be connected to P1 and P2 on the MJ93BK

The alarm relay 1 connections 15 (Common), 16 (NC), 18(NO) replace connections 21(Common), 22(NC), 24(NO) on

the TCP-M2

The alarm relay 2 connections 25 (Common), 26 (NC), 28(NO) replace connections 31(Common), 32(NC), 34(NO) on

the TCP-M2.

NOTE: Connections Y1 and Y2 are used to select Manual or Auto-reset after a Thermistor alarm. Check the DIP

switch settings on your TCP-M2 and verify the required function.

IF YOU ARE NOT SUITABLY QUALIFIED TO REPLACE YOUR TCP-M2 WITH THIS KIT YOU ARE

STRONGLY ADVISED TO FIND A COMPETENT ENGINEER.

For Remote reset operation connect a switch across Y1 and Y2 terminals, Device will be in Auto reset mode ,if switch is open ,other wise device will be in Manual reset mode.

If fault occurs and recovers while the device is in Manual Reset mode, then user can put the device in Auto mode temporarily and switch ON the realy and Put the device back in Manual Reset mode, So, attending the decive can be avoided.

For Auto reset operation, keep Y1 and Y2 terminals open . Device will reset automatically when the total loop resistance of the series connected thermistors drops below 1.6 k +/5%. Ù

Probe cable open Circuit detected by device if resistance is above 10k + and cannot reset until resistance is lower then 1.6 k + 5 % The resistance at 25C0 of probe circuit must be with in 40 < 1.5 k range.

Thermistor Relay protects and controls motors and alternators fitted with PTC ther mistorsensors. Motorheating is directly measured by temperature sensors that are in corop orated in starter windings. This ensures a direct control in following, operating.Conditions: heavy duty high, switching frequence, single phasing, high ambient temperature and insufficient cooling. This really disconnects when probe resistance exceeds 3.6 k + 5% and cannot reset until resistance lower then 1.6 k,+5% Auxiliary supply voltage should be applied to device between terminals A1-B2 to product ,connection. The relay trips through probe heating, resetting may be AUTO ,MANUAL or REMOTE.

Ù

Probe cable short circuit is detected by device if resistance is lower then 20+4 and resets when probe resistance is greater then 40 + 4.

ÙÙ Ù

For Manual reset operation , keep Y1 and Y2 terminals short. Device will reset manually by pressing RESET key of device when the total loop resistance of the series connected thermistors drops Below 1.6 k +/-5%.

Thermistor Relay protects and controls motors

and alternators fitted with PTC thermistor sensors.

Motor heating is directly measured by temperature

sensors that are incorporated in starter windings.

This ensures a direct control in following operating

conditions: Heavy duty, high switching frequency,

single phasing, high ambient temperature and

insufficient cooling. Relay connection between 15

and 18 disconnects when probe resistance exceeds

3.6 k and cannot reset until resistance lower

than 1.6 k . Auxiliary supply voltage should

be applied to device between terminals L1-L3 to

produce connection.

Thermistor Functionality:

3 Phase Functionality:

Product is designed to detect phase sequence in

three phase power system. When phase sequence of

three phase is correct (L2 with 120 lag with respect

to L1 and phase L3 with 120 lag with respect to L2),

then relay connection between terminals 25 and 28

closes. Otherwise contacts are open.

AUTO RESET: For AUTO Reset operation, keep pot

position on AUTO. Device will reset automatically

when total loop resistance of series connected

thermistors drops below 1.6 5%.kΩ ±

MANUAL RESET: Manual reset can be reached by

keeping the pot on MANUAL. Device will reset

manually by changing pot position to AUTO. When

the total loop resistance of series connected

thermistors drops below 1.6 k 5%.Ω±

Control relay for phase failure and thermistor protectionThe TCP-M2A monitors phase sequence, phase failure and phaseasymmetry, and is used with PTC sensors to provide over temperatureprotection for motors and other equipment.

If a failure is occured, the relays are deenergised after theadjustable time tr (0,1s..10s).

R2 switch on, when all phases are detected, the phase sequence is correct,all phase voltages are in the range of Un +/-10% and the phase asymmetryimbalance < 10%.

R1 switch on, when the resistance of the PTC sensors on the input T1 - T2is within the correct range.

R1 switch on, if the resistance of thePTC is in the correct range and afterthe time delay of te (0..30min).

R2 switch immediately on, if allparameters are in the specifiedrange.

The control relay will detect a phasefailure even with a regeneratedvoltage present on the failed phase(no detection on request).
