Section 6

ATM200 Actuator Issues

1. Andrew requires pretesting actuators on the ground prior to installation,

using the Andrew portable controller and the latest version of the

controller software (available online at www.andrew.com under Products

→

Antennas→Teletilt

RET System). This will verify proper actuator

functionality and also ensure that the latest available actuator ﬁ rmware

release is installed on the actuator. Failure to conduct pre-test and pre-

installation procedures deﬁ ned by Andrew will void warranty.

2. Unauthorized removal of a protective shroud to replace actuators voids

the Andrew warranty.

These instructions are speciﬁ c to the external actuator such as ATM200-002 or ATM200-A20.

6.1 No Actuators Found

• Verify all RET control cables are correctly connected.

• Bypass ﬁ rst actuator in a daisy chain to see if ﬁ rst actuator is a problem.

• Assure that surge arrestor passes dc (typically APTDC-BDFDF-DB or APTDC-BDFDM-DB).

• Isolate and eliminate good devices in path (Section 5) until problem device is found.

• Check output voltage of smart bias tees and smart TMAs that need to have 10 to 30 Vdc between

pins 1 and 6. See Table 2-2 for pin-out.

• Use ATTK200-KIT to test for damaged home run RET cable or jumper, or test using known good

cable.

• Check male connector of ﬁ rst actuator in a daisy chain. If key does not point to center of actuator,

connector may have been twisted so that pins have no internal contact.

After the checks listed above, see also:

• If using ATC200-LITE-USB, see Section 7.1.

• If using ATC300-1000, see Section 8.1.

• If using SMB ports on ATC300-1000, see Section 9.1

• If using ATC200-1000, see Section 10.1.

6.2 Not All Actuators Found

• Turn off power to controller. Turn on again and rescan to assure correct bus addressing (i.e., all

addresses are unique).

• Isolate and verify which actuators function properly (Section 5).
