4.7.4. Analog Outputs
Two analog outputs are available, and may be used for 0 – 10 Volt Signal (max load 20mA), 0 – 20mA, 4 – 20mA or a digital
+24Volt DC, 20mA output. The parameters to select function and format are as follows.

These parameters are described more fully in section
8.1. Digital Input Configuration Parameter P1-13
4.7.5. Auxiliary Relay Outputs
Two relay outputs are available, which are intended to be used to switch external resistive loads up to 5A at 230 VAC or 30VDC.
Relay 1 has both normally open and normally closed contacts available. Relay 2 provides a simple open or closed contact.
The relay output function may be configured using parameters P2-15 and P2-18, which are described in section
4.8. Motor Thermal Overload Protection
4.8.1. Internal Thermal Overload Protection
HP Combi Flow has internal motor overload protection (current limit) set at 150% of FLC. This level may be adjusted using P4-07.
The drive has an in-built motor thermal overload function; this is in the form of an “I.t-trP” trip after delivering >100% of the value set in
P1-08 for a sustained period of time (e.g. 150% for 60 seconds).
4.8.2. Motor Thermistor Connection
Where a motor thermistor is to be used, it should be connected as follows:

Compatible Thermistor: PTC Type, 2.5kΩ trip level.
Use a setting of P1-13 that has DI5/AI2 function as E-TRIP
“External Trip”, e.g. P1-13 = 6. Refer to section
Input Configuration Parameter P1-13
