TIM Time Not Set
Cause Possible Solution
The Real-Time Clock for the HOA keypad
is not set in parameter o4-17 and a feature
that requires RTC information is enabled.
• The drive is a new drive, first power-up

• o4-17 was set to 2, Reset, by the user,
manually clearing the Real-Time Clock
data.
Set o4-17 to 1 to set the time for the HOA keypad.
The drive will display the "Clock Not Set" alarm when the Real time Clock is not set. Additionally, at power
up, if the "TIM" condition is present, the drive will automatically switch to the time setting screen (o4-17 =
1) for 30 seconds to prompt the user to set the Real-Time Clock.
The user did not set the Real Time Clock
when prompted following power-up.
Cycle power to the drive and set the Real Time Clock within 30 seconds of power-up, or set the clock
manually via parameter o4-17.
The HOA keypad battery is low or the
battery has been replaced.

TLGI Geothermal Input
Temperature Lost Geothermal Input
The geothermal input is not present.
Cause Possible Solutions
The input signal level has dropped below
3 mA or risen above 21 mA when the drive
was running and b1-01 = 5, H3-0o = 21
(Geothermal Input), H3-0o = 2
(4 to 20 mA), and Q2-09 = 2 (Fault).
Confirm that the device connected to the analog input terminal is installed and working properly.
The drive was running while b1-01 = 5,
H3-0o ≠ 21 (Geothermal Temp), and
Q2-09 = 2 (Fault).
Assign one of the analog inputs to “Geothermal Temperature”, H3-0o = 21.
