7.5.14.8 Manual/remote changeover
Only “HVAC” controllers
Function - With manual/remote changeover (H/Re), it is for instance possible to change from remote
operation to manual operation in the event of setting-up the drive or service.
- For manual operation, the remote operation must not be changed (e. g. LECOM).
- In manual operation, the setpoint is entered via potentiometer or motor potentiometer.
- The function “Motor potentiometer” is activated via terminal E1 ... E4.
- If the function “Motor potentiometer” is activated, the operating mode is set to
C001-internal = -0-.
- The change between manual and remote operation can only be carried out through terminals
E1 ... E4. The following changeover is possible:
- Fieldbus
 Function “Motor potentiometer”
- Fieldbus  Analog terminal setpoint (terminal 8, terminal E1, additional setpoint)
- Function “Motor potentiometer”  Analog terminal setpoint (terminal 8, terminal E1, additional
setpoint)
Activation C007 = -47-:
- HIGH level at terminal E2
- Manual operation, function “Motor potentiometer” is active, C001-internal = -0-
- Setpoint selection via analog channel
C007 = -23-, -24-, -25-, -26-, -27-:
- HIGH level at terminal E4
- Manual operation, function “Motor potentiometer” is active, C001-internal = -0-
- Setpoint selection via UP (term. E2), DOWN (term. E1)
C007 = -46:
- HIGH level at terminal E4
- Manual operation, function “Motor potentiometer” is active, C001-internal = -0-
- Setpoint selection via analog channel
C007 = -23-, -24-, -25-, -26-, -27-, -46-, -47-:
- LOW level at terminal E2 (if C007 = -47-) or terminal E4
- Remote operation, function “Motor potentiometer” is not active, C001-internal = C001
- Setpoint selection via C046, analog channel or JOG frequency
The signal level is indicated for C114 = -0- (see chapter 7.5.14.1).
Important Safety functions ctrl. inhibit and QSP activated in remote operation are reset when changing to
manual operation. Check, whether the master sets these safety functions again when changing
from manual operation to remote operation.
