CONTROL PANEL SULZER APC 1/2B
USER GUIDE
Rev.13 (2018/08/30)
2.3.
SCOPE. DEVICES AND FEATURES
(ENCLOSURE AND POWER EQUIPMENTS)
-
Metallic enclosure IP54 after pilot installation.
-
Three phase main switch (AC21) with door handle allowing disconnecting voltage supply from
outside before to open the control panel door.
-
Motor circuit breaker to every pump power output. MCB used in APC have thermal trip regulation
according to the pump power load.
-
Earth leakage switch to every pump power output. For pumps smaller than 38 Amps motor
consumption, these earth leakage switches have a fixed trip point at 0,3 Amps
.
-
Available with DOL, START-DELTA, Soft Starter and VFD as a method to run the motor.
2.4.
SCOPE. DEVICES AND FEATURES (CONTROL CIRCUITS AND EQUIPMENTS
)
-
Advanced control system with graphic display ABS PC 242, door mounted to allow an easy setting
up and use of the system.
-
Ready to work with analogue sensors (0-20 or 4-20mA) or floats. Normally you will receive an offer
of an APC version that includes devices for level measurement or level floats (as required).
-
Door mounted selectors to run manually each pump (with no relation of what PC 242 does)
-
Emergency control circuit that works over the PC 242 in case of failure of the level normal
measurement system, in APC basic version; and made by relays, allowing working even if PC 242
were broken down, in APC complete version.
-
Ready to receive a thermal sensor signal from each pump, that could be bimetallic type, PTC or
PT100. PC 242 has an internal module to manage PTC and PT100 signals built in, what allows to
indicating the current temperature the sensor measures, and set alarm set points.
-
Ready to receive a leakage sensor signal from each pump. PC 242 has an internal signal
conditioner for ABS leakage signals built in, what allows to monitor the pump state and set alarms.
-
Digital voltmeter door mounted
-
Electronic amp meter built in PC 242 to monitor puma status and set alarms (only available in
complete version of APC).
-
General reset push button.
-
Synoptic to show how the pump pit works, with LED pilots to see what pumps are running and if
the high level float is activated. This synoptic incorporates the selectors to choose the pump mode
operation (MANual-0-AUTOmatic), and another selector that allows choosing pumps that will work
with the emergency control system (last selector only available in complete versions of APC).
-
Indication of general alarm, pump 1 alarm and pump 2 alarm, via 3 dry contacts
-
SELV control circuit type, with 24Vdc
to feed controller, sensor, floats, pump signals,…
-
With two RS232 serial ports. One of them to connect directly a computer using a DB9 standard
plug for service; and the other for direct/radio/GSM/GPRS/OpticFiber/… communication,
connecting the modem to PC 242 terminals
