Safety Equipment; Alarm Messages - REGLOPLAS P140M Betriebsanleitung

3 All applicable guidelines and safety regulations shall be followed when connecting the unit to the mains.
2.5.1 Interface cable and optional equipment (Fig. 1 and 2)
If the unit is equipped with an interface, its cable must be fed beneath the electrical housing door. When moving the unit,
ensure that the rollers do not roll over the cable.

2.6 Safety equipment

In addition to the usual safety equipment, such as electrical overload protection of the pump motor, safety thermostat, level
monitor and filter, the unit is equipped with the following monitoring equipment to ensure safe and reliable operation:
– Pressure gauge:
In Models P140M and P160M(D), the pressure gauges show the pressure in the outlet hoses and the system pressure, which is
comprised of the pressure caused by the expansion of the water and the saturated vapour pressure.
– Pressure relief (P140M and P160M[D]): The RT50 control system provides pressure relief by automatically switching to
pressureless operation at temperatures below 60 °C. (This value can be decreased, depending on the value of the run-out
temperature programmed. See the RT50 Programming Instructions, Section P 4.3).
Additional pressure relief occurs when the unit is switched to OFF. This guarantees that the unit is free of pressure after it is
switched off, despite any back pressure in the drain.
– Bypass: Prevents the pump from damage (running dry) due to e.g. a closed shut-off valve in the consumer circuit.
– Safety valve (P140M and P160M[D]): Set pressure 10 bar (→ Service).
– Pressure sensor: Measures and regulates the system pressure when operating under pressure, thus ensuring constant
pressure-blanketing.
– Pressure limiting: Water expands during heat-up. If the unit's expansion chamber is too small, the water flows through the
pressure-relief valve (Y8) into the cooling water drain.
The temperature of the cooling water exiting the system can reach that of the heat-transfer fluid
2.7 Switching on
Open the vent valve at the consumer as well as the shut-off valve (when present).
After checking the consumer, connecting the hoses, establishing the electrical connections,
and opening the shut-off valves in the outlet and inlet, proceed as follows:
2.7.1 Switching on with the RT32 control system (Gefran 1200) (Fig. 3, Table 1)
Model 90M only: Switch the unit/pump on using the corresponding switch.
Once the unit has been switched on, the RT32 (Gefran 1200) will run a functional
test for approximately 2 seconds.
During this test, all displays will blink. Once the test has been completely successfully,
the actual value will appear in the upper display field and theset-point value in the lower.
The unit will now fill with water automatically.
Ensure that the pump's direction of rotation corresponds to the arrow.
If the direction of rotation is incorrect, switch the phases on the unit's plug.
Check for leaks in the temperature control circuit (unit, connection hoses, consumer, etc.).
Close the vent valve once water flows out of it regularly.
The unit will switch on again automatically after a power outage.
2.7.2 Setting elements
Enter the set-point value using the ∆ and ∇ keys.

2.7.3 Alarm messages

In the event of a break in the sensor, "Sbr" will appear in the display; in the event of a short circuit in the sensor, "Err" will
appear in the display.
In both cases, cooling will be switched on automatically to protect the consumer from overheating (Indicator light "OUT 2").
