| Mounting | For mounting on an inner door, use 11 Pin Back-Mounted Socket (IDEC SR6P-M11G which is provided with the relay). For panel-mounting, use industry-standard 11 Pin Octal socket (Macromatic 70170-D or equivalent). |
| Series Features |
| TCF-F Series for Pumps with FLS or CLS Leakage Sensor OVER TEMPERATURE & SEAL LEAKAGE |
| Series Description: Macromatic TCF-F Series products monitor for over temperature and seal leakage on Flygt submersible pumps using either FLS or CLS leakage sensors (MINI-CAS). These units come with a switch to select either automatic reset or manual reset for an over temperature condition. The flange-enclosure is designed to be mounted on an inner door and used with a back-mounted 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 flow 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, theunit will reset automatically. In the MANUAL mode, the Over Temp Reset button must be pushed toclear the alarm and reset the relay. In a seal leakage condition, contaminating fluid 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 flashing the corresponding Red TEMP LED or Red SEAL LED. The flashing 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 flashing the Red SEAL LED and the Red TEMP LED. If the short is removed, the fault will automatically reset within 30 seconds. |
