OVER TEMPERATURE & SEAL LEAKAGE

Auto & Manual Reset | TCF-F Series for Pumps with FLS or CLS Leakage Sensor

Macromatic TCF-F Series products monitor for over temperature and seal leakage on submersible
pumps using either FLS or CLS leakage sensors. These units come with a switch to select either
automatic reset or manual reset for an over temperature condition.

The f ange-enclosure is designed to be deadfront-mounted on an inner door and used with a back­mounted socket (included). Everything needed for setup, use and troubleshooting is on the top of
the unit: status LEDs, switch to choose Automatic or Manual Reset mode for temperature, and a
pushbutton for Manual Reset of an over temperature condition. They are all visible so that the door
need not be opened to see the status of the over temperature or seal leakage condition.

Operation:

Two wires from the relay are connected to the FLS or CLS sensor which is in series with the pump
over temperature switch. A low-voltage DC signal is applied to measure the current f ow through
the sensor and over temperature switch. The sensor controls the current in this circuit. These

products have isolated output contact relays, one for over temperature and one for seal leakage.

With input voltage applied, normal temperature condition (thermal switch closed) and no seal
leakage, the sensor current will be in the normal range. The over temperature relay is energized
and the seal leak relay is de-energized. Both LEDs are Green, indicating normal conditions and
input voltage applied.

When the motor temperature rises and the N.C. thermal switch opens, the sensor current drops
to zero. The over temperature relay is de-energized, opening a contact that had been closed and
turning off the pump contactor. The TEMP LED turns Red. If the over temperature condition is
cleared, the unit will reset based on the setting of the Over Temp switch. In the AUTO mode, the
unit will reset automatically. In the MANUAL mode, the Over Temp Reset button must be pushed to
clear the alarm and reset the relay.

In a seal leakage condition, contaminating f uid enters the pump motor cavity. The sensor lowers its
resistance, increasing the sensor circuit current above the trip point. The seal leakage output relay
energizes and closes a contact, which can be used to give an alarm indication of a leaking seal.
The SEAL LED turns Red.

Cleared Fault Condition
If either an Over Temp fault condition when the Over Temp switch is set to AUTO or a Seal
Leakage fault has been automatically cleared, a cleared fault indication is displayed by f ashing the
corresponding Red TEMP LED or Red SEAL LED. The f ashing indication may be manually reset
by pressing the Over Temp Reset button. Note: if either fault still exists when the Over Temp Reset
button is depressed, it is ignored.

Shorted Sensor
If the sensor wires are shorted, the unit will display a Shorted Sensor condition by alternately
f ashing the Red SEAL LED and the Red TEMP LED. If the short is removed, the fault will
automatically reset within 30 seconds.

LED Indicator:
T emp: Green ON with input voltage applied, normal temperature

condition and relay energized; Red ON when over temperature
detected and relay de-energized; Red Flashing when over
temperature condition has been cleared in AUTO mode

Seal: Green ON with input voltage applied, no seal leak and relay
de-energized; Red ON when seal leak detected and relay energized;
Red Flashing when seal leakage condition has been cleared

Shorted Sensor: If sensor wires are shorted, TEMP & SEAL
LEDs will alternately f ash Red

Mounting:

For deadfront-mounting on an inner door, use 11 Pin Back-Mounted
Socket (Custom Connector OR11-PC which is provided with the relay). For
panel-mounting, use industry-standard 11 Pin Octal socket (Macromatic
70170-D or equivalent).
