17.15 Activation delay

Pump variant
TPE3, TPE3 D
TPE2, TPE2 D
Select the activation delay, T1.
It is the time between the digital signal and the activation of the
selected function.
Range: 0 to 6000 seconds.
Duration timer mode
Select the mode. See fig. 58.
• Not active
• active with interrupt, mode A
• active without interrupt, mode B
• active with after-run, mode C.
Select the duration time, T2.
It is the time which, together with the mode, determines how long
the selected function is active.
Range: 0 to 15,000 seconds.

17.16 "Signal relay 1 and 2" (Relay outputs)

Pump variant
TPE3, TPE3 D
TPE2, TPE2 D
Function
Relay output 1
Relay output 2
* See section 9.5.1 Connection terminals, advanced functional
module, FM 300.
The pump incorporates two signal relays for potential-free
signalling. For further information, see section
Function
You can configure the signal relays to be activated by one of the
following incidents:
• Not active.
• Ready
The pump can be running or is ready to run and no alarms are
present.
• Alarm
There is an active alarm and the pump is stopped.
• "Operating" (Operation)
"Operating" equals "Running" but the pump is still in operation
when it has been stopped due to a warning.
• "Running" (Pump running)
• Warning
There is an active warning.
• Digital input 1, state
Follows digital input 1. If digital input 1 is activated, output is
also activated.
• Digital input 2, state
Follows digital input 2. If digital input 2 is activated, output is
also activated.
• Digital input 3, state
Follows digital input 3. If digital input 3 is activated, output is
also activated.
• Digital input 4, state
Follows digital input 4. If digital input 4 is activated, output is
also activated.
• Limit 1 exceeded
When the Limit 1 exceeded function is activated, the signal
relay is activated. See section
• Limit 2 exceeded
When the Limit 2 exceeded function is activated, the signal
relay is activated. See section
• Relubricate
• External fan control (Control of external fan)
When you select "External fan control", the relay is activated if
the internal temperature of the motor electronics reach a
preset limit value.
