OVER TEMPERATURE & SEAL LEAKAGE

Auto & Manual Reset | TCF-E Series for Pumps with Float Type Leakage Detector

Macromatic TCF-E Series products monitor for over temperature and seal leakage on
submersible pumps using a f oat type leakage detector
switch to select either automatic reset or manual reset for over temperature.

The f ange-enclosure is designed to be deadfront-mounted on an inner door and used
with back-mounted sockets. Everything needed for setup, use and troubleshooting is
on the top of the unit: status LED, 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 Over Temp/Seal Leakage relay are connected to a N.C. thermal
switch in the windings of the pump motor to monitor for overheating. A low-voltage
DC signal is applied to check the status of the thermal switch. Two additional wires
are connected to a N.C. f oat switch in the Leakage Sensor. A separate low-voltage
DC signal is applied to check the status of the Leakage Sensor. 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 (Leakage Sensor contact closed), both the over temperature relay
and the seal leakage relay are energized. The TEMP & SEAL LEDs are both Green,
indicating normal conditions and input voltage applied.

When the motor temperature rises and the N.C. thermal switch opens, 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.

If the seal starts to leak, contaminating f uid enters the pump motor cavity. The contact
in the Leakage Sensor will open and the seal leakage relay is de-energized, reclosing
a contact that was opened and providing an alarm indication of a leaking seal. The
LEAK LED turns Red.
